Abstract:
Disclosed are server features for allowing a client user to defer completion of multi-step user transaction applications (“MUTAs”) and later resume the MUTA. One disclosed feature is providing a selectable deferral action in a page implementing part of the MUTA, e.g., HTML, XML, JavaScript/ECMA Script document. If the client user selects to defer completion, a state object is created by the server and stores state information including information previously entered during the MUTA. The server provides a resumption object to the user including a resource for resuming the deferred MUTA. When the user selects the resource, state information stored in the state object is loaded and the use may complete the remainder of the MUTA. An additionally disclosed aspect is automatic state saving where sate information is stored automatically during multiple steps in the MUTA; the user then need not select deferral.

RELATED APPLICATION 
     Subject matter in this application may be used in conjunction with subject matter described in a commonly owned patent application entitled “A Method, Apparatus, and Computer Program Product For DEFERRED COMPLETION OF MULTI-STEP USER TRANSACTION APPLICATIONS” naming Jay C. Weber and Caius van Nouhuys as inventors, which is filed concurrently herewith and assigned application Ser. No. 09/364,170 and which is incorporated herein in its entirety by this reference. 
     FIELD 
     Aspects of the invention relate generally to server architectures for transaction processing and more particularly to architectures with features allowing user control over the timing of the completion portion of transaction processing. 
     BACKGROUND 
     The collection of protocols and applications commonly referred to as the World Wide Web (“Web”) is a widely used client-server architecture for transaction applications. The convenience of carrying on transactions with Web applications is leading to an increasing portion of the transactions persons engage in day-to-day being performed with Web applications. 
     Typically, transaction applications involve many steps each with its own page. The network user generally must interact must with each page of the transaction application. When such a multi-step user transaction application (hereinafter “MUTA”) is started by the user, they may not have expected the MUTA to require as many steps as it does, or some other activity may interrupt the user&#39;s ability to complete the MUTA at the current time. This is particularly true with increasingly popular platforms where, for instance, Web applications, are combined with televised entertainment. Such platforms are frequently known as “Enhanced TV” or “Interactive TV” (hereinafter “ITV”). In such a context, a viewer of a video program may be prompted by a Web resource enhancing the video program to initiate a transaction. However, the user may wish to return to viewing the video program quickly and not wish to spend the time to complete the transaction at that moment. Thus it would be desirable for a mechanism to exist that allowed the user to defer completion of such a transaction. 
     Related series of technologies include user registration systems. In a typical user registration system, a user provides information to the operator of, for instance, a Web application. The user may be able to pre-specify information that is relevant to a later interaction during the registration process. However, the registration information that is stored cannot provide information that would allow a user to return to the precise position in a later-initiated transaction where the user decided to defer completion. Put another way, while user data stored, for instance as part of a registration process, may be relevant to a later transaction and form part of the state of the transaction at any particular step, user registration data does not provide full state information for later-initiated transactions. Accordingly, stored registration data technologies are unable to provide a system for preserving state of a MUTA to allow deferred completion and resumption. 
     An additional aspect of conventional technologies is that conventional Web applications lack a convenient mechanism to defer completion at any point of a transaction. Many conventional electronic commerce applications operate on a ‘shopping cart’ model. In a typical ‘shopping cart’ model application, a user will interact with an ‘electronic store’ of some sort: browsing items, comparing product features, searching, etc., and then add items the user wishes to purchase to an electronic ‘shopping cart’. When the user wishes to complete their interaction at the ‘electronic store,’ the user so indicates and the items ‘in’ their ‘shopping cart’ are processed to consummate the transaction. Many ‘shopping cart’ applications provide the feature that a user can return to their ‘shopping cart’ with the state preserved, i.e., the items they have previously ‘in’ their ‘shopping cart’ will still be there. However, the ‘shopping cart’ is but one part in an overall shopping application: users do not have the ability to return directly to other points in the overall process, for example a particular page providing information about a product&#39;s features. As the type and nature of Web transactions becomes more complex, and as less sophisticated users carry on such transactions, a need has arisen for a general solution to the problem of allowing a user to defer completion of MUTAs at any step in the overall interaction and resume the interaction at that stage at a later time. 
     SUMMARY 
     In order to provide a solution to the forgoing and additional problems, aspects of our invention provide a method, apparatus, and computer program product for deferred completion of multi-step user transaction applications. 
     One aspect of the invention involve computer-implemented methods for deferring completion of a multi-step user transaction application. An illustrative method includes providing a page to a client application. The page includes one or more resources for input of information related to completion of the MUTA, and a resource for selection of a deferral action. The method also includes receiving an indication of the selection of the deferral action, storing state information (including a position in the MUTA and information related to completion of the MUTA); and generating a resumption object including an identifier of a resource for completion of the MUTA. Storing state information can be performed automatically at more than one step in the MUTA and storing state information can be performed in response to user selection. In addition storing state information may include monitoring an elapsed time since a transaction page was provided; determining whether the elapsed time exceeds a predetermined time limit; and storing state information if a user response is received within the predetermined time limit. In an further step, the resumption object is transmitted to a client application. 
     An additional variation of the illustrative method includes a computer-implemented method for completing a previously-deferred MUTA. The computer-implemented method includes providing a resumption object to a client application. The resumption object here includes an identifier of a resource for completion of the MUTA. Additional steps in the method include receiving a request for the resource for completion of the MUTA; retrieving previously-received information for returning to a state at which the MUTA was previously deferred; and providing a resource corresponding to the state at which the MUTA was previously deferred. 
     Yet another aspect of the present invention are computing apparatuses for deferring completion of a multi-step user transaction application. An illustrative computing apparatus with a processor, a memory, and an input/output system includes server process logic configured for providing a page to a client application, the page including one or more resources for input of information related to completion of the MUTA and a resource for selection of a deferral action. The server process logic is further configured for receiving an indication of the selection of the deferral action, and generating a resumption object comprising an identifier of a resource for completion of the MUTA. The computing apparatus also includes a data storage system configured for storing state information including a position in the MUTA, and information related to completion of the MUTA. In a variation, the server process logic is configured for storing state information in the data storage system at plural steps in the MUTA; and, the illustrative apparatus may inclde process logic configured for monitoring an elapsed time since a transaction page was provided. In yet another component, the server process logic is further configured for transmitting the resumption object to a client application. 
     An additional variation of the illustrative apparatus includes a data storage system configured for storing a state object and server process logic configured for providing a resumption object to a client application. The resumption object includes an identifier of a resource for completion of the MUTA. The server process logic is also configured to receive a request for the resource for completion of the MUTA, retrieve previously-received information from the state object for returning to a state at which the MUTA was previously deferred, and provide a resource corresponding to the state at which the MUTA was previously deferred. 
     Yet another aspect of the invention are computer program products including a computer-readable storage medium having computer-readable program code embodied therein for deferring completion of a multi-step user transaction application. Illustrative computer-readable program code includes code for providing a page to a client application. The page includes one or more resources for input of information related to completion of the MUTA, and a resource for selection of a deferral action. The computer-readable program code also includes code for receiving an indication of the selection of the deferral action, code for storing state information (including a position in the MUTA and information related to completion of the MUTA), and code for generating a resumption object comprising an identifier of a resource for completion of the MUTA. The code for storing state information may also include code for storing state information and two or more steps in the MUTA. The code for storing state information may include code for monitoring an elapsed time since a transaction page was provided; code for determining whether the elapsed time exceeds a predetermined time limit; and code for storing state information if a user response is received within the predetermined time limit. 
     An additional variation on the illustrative program product includes a computer-readable medium having computer program code embodied therein, the computer program code including code for providing a resumption object to a client application. The resumption object includes an identifier of a resource for completion of the MUTA. The computer program also includes code for receiving a request for said resource for completion of the MUTA, code for retrieving previously-received information for returning to a state at which the MUTA was previously deferred; and code for providing a resource corresponding to said state at which the MUTA was previously deferred.

     DETAILED DESCRIPTION 
     Description of Figures 
       FIG. 1  depicts elements in an operating environment  1000  in accordance with an illustrative embodiment. Shown are a client application  1100  and a server process  1300 . The client application  1100  and the server process  1300  are configured for client-server communication across a data network  1200 . In some embodiments, the data network  1200  comprises a portion of the Internet, although other networks could be used, either public or private, and using either the TCP/IP protocols (including the User Datagram Protocol) or with other protocols. In preferred embodiments the Hypertext Transfer Protocol (“HTTP”) is used to communicate Request and Response messages and Hypertext Markup Language (“HTML”) pages. 
     In some embodiments, the client application  1100  executes on a hardware platform that integrates the features of a television receiver and network connectivity. Many commercially available structures can perform these functions. Certain of the current generation of “set-top boxes” are suitable, including, for instance, the WebTV “Plus” set-top box (also known as an Internet Receiver available through Microsoft&#39;s WebTV Networks, Inc. of Palo Alto, Calif. (and their manufacturing licensees). In other embodiments, the client application could execute on a general purpose computer configured with suitable video hardware to integrate the features of a television receiver and network connectivity. As one skilled in the art will appreciate from this disclosure, the features of the invention are not limited to embodiments which operate with client platforms that integrate television and network connectivity. However, the features of the invention obtain particular benefits in this context. 
       FIG. 2  depicts a computer system  2000  capable of embodying aspects of the invention. The server process  1300  may execute on structures in accordance with the computer system  2000 . The computer system  2000  comprises a microprocessor  2010 , a memory  2020  and an input/output system  2030 . The memory  2020  is capable of being configured to provide a data structure  2040  which may contain data manipulated by the computer system  2000  when embodying aspects of the invention. Further illustrated is a media drive  2070 , such as a disk drive, CD-ROM drive, or the like. The media drive  2070  may operate with a computer-usable storage medium  2075  capable of storing computer-readable program code (“code”) able to configure the computer system  2000  to embody aspects of the invention. The input/output system  2030  may also operate with a keyboard  2050 , a display  2060 , a pointing device  2090 , or a network such as the data network  1200 . The input/output system  2030  may also communicate with a mass data storage  2080  such as a database or the like. The mass data storage  2080  may store information related to users of the client application  1100  that facilitate completion of MUTA, including, for instance, user profile information, records of past interactions, payment instrument information, demographic information, product or service feature preference information, or the like. 
     As illustrated, the computer system  2000  is general-purpose computing machinery. As one of skill recognizes, programmed instructions may configure general purpose computing machinery to embody structures capable of performing functions in accordance with aspects of the invention. Special purpose computing machinery comprising, for example, an application specific integrated circuit (ASIC) may also be used. In addition, the computer system  2000  could be diskless and operate with a non-volatile memory. Further, configurable hardware could be used including, for instance, a field programmable gate array, or a complex programmable logic device. One skilled in the art will recognize, numerous structures of programmed or programmable logic capable of being configured to embody aspects of the invention. In some embodiments, the computer system  2000  is a SPARC-based workstation from Sun Microsystems of Mountain View, Calif., running the SOLARIS operating system and the Apache HTTP server with a Secure Sockets Layer module. In such embodiments, the server process  1300  could comprise the Apache HTTP server with the Secure Sockets Layer module. 
     The client application  1100  (under the direction of a user) may communicate with the server process  1300  to carry out a MUTA. The user transaction application may be a commercial transaction (sometimes referred to as “E-Commerce”), although one skilled in the art is familiar with many other user transaction applications conventionally practiced in, for instance the Internet environment. 
     Typically MUTAs involve many steps, each with its own page(s). The user may not have expected so many steps when initiating the MUTA, or some other activity may interrupt the user&#39;s ability to complete the application at the current time. This is particularly true of ITV combinations of World Wide Web applications and televised entertainment where the user may wish to return to watching television full-screen before the interactive aspects of the application are completed. 
       FIG. 3  depicts a deferred completion state diagram  3000  illustrative of various embodiments of the invention. The deferred completion state diagram  3000  is a high level representation of the context in which features of the invention may be advantageously employed. As depicted in  FIG. 3 , states and transitions of a MUTA are shown. When a user initiates the MUTA a first state  3100  is entered. The first state  3100  may be understood on differing levels of generality, from the first page provided from the server process  1300  to the client application  1100 , to greater levels of generality including parameters relevant to the MUTA and/or their values. Without deferral, the MUTA proceeds though a first to second state transition  3800  to a second state  3200 , though a second to third state transition  3850  to a third state  3300 , etc. until a last or Nth state  3400  is entered and the MUTA completes. For similar transactions, one ordinarily expects the number of pages of forms in a transaction to be greater when the client platform is an enhanced or interactive television device than when the client platform is a conventional PC-based browser. The number of states at which a transaction could be deferred would typically grow along with the number of pages of forms in the transaction. 
       FIG. 3  also depicts a deferred state  3500  entered through a deferral transition  3600 . For instance, if the second state  3200  were the second page of the MUTA, the user could elect to defer completion of the MUTA and transition from the second state  3200  to the deferred state  3500  with the deferral transition  3600 . Once deferred, the MUTA remains in the deferred state  3500  until the user decides to complete it. When the user decided to complete it, a resumption transition into the second state  3720  would return the MUTA to the second state  3200 —the position from which the user entered the deferred state  3500 .  FIG. 3  illustrates this with a parenthetical notation of the resumption transition given the position at deferral, e.g. (R|P=2) for “Resume given that position at deferral was state  2 ”. The user could then proceed to complete the MUTA from the second state  3200 .  FIG. 3  also shows a resumption transition into the third state  3730  and a resumption transition into the Nth state  3740  indicating that the features of the invention provide for deferral and resumption from any state of the MUTA. 
       FIG. 4  depicts an data architecture  4000  in accordance with an illustrative embodiment. In this illustrative embodiment, the server process  1300  configures the memory  2020  of the computer system  2000  to provide the data structure  2040  in accordance with the data architecture  4000  for deferral and resumption of MUTAs. In other embodiments, information stored in the data architecture  4000  could be stored in the mass data storage  2080  and maintained with a conventional database management system. The data architecture  4000  comprises, for instance a table or tree, keyed by a user identifier  4100 . The user identifier  4100  could be an identifier of a user associated generally with an account maintained by an operator of the server process  1300 , could be established on a per-transaction basis, could be a more general form of personal identification information such as a PIN number, or other identifier.  FIG. 4  also depicts a first transaction state object  4200  comprising a transaction identifier  4210 , a position identifier  4220 , and a set of field/value pairs  4230 . State objects such as the first transaction state object  4200  are created in accordance with the illustrative embodiment when deferred completion of the MUTA is elected by the user. 
     The transaction identifier  4210  is an identifier of a particular transaction for which deferred completion has been elected. A user may defer completion of plural transactions, as illustrated by a second transaction state object  4300  and a Nth transaction state object  4400 . The transaction identifier  4210  in the first transaction state object  4200  distinguishes the transaction associated with the first transaction state object  4200  from those associated with the second transaction state object  4300  or the Nth transaction state object  4400 . 
     The position identifier  4220  in the first transaction state object  4200  identifies a position in the flow of steps the MUTA comprises to which the user should be returned when resuming the MUTA. The position could be the position at which the user elected deferred completion; the position could also be context-sensitive and, for instance, return the user to a contextually-appropriate prior step. When, for instance, the MUTA is implemented through one or more text markup language documents, e.g. HTML pages, the first transaction state object  4200  may conveniently be a URI. 
     The set of field/value pairs  4230  in the first transaction state object  4200  stores data fields and associated data field values relevant to completion of the MUTA that have been made available up to the point at which completion deferral was elected. This may include, for instance, user data input as part of the MUTA, data from the user from previous transactions, data obtained from other sources, e.g., user profile information, accounting information internal to the operator of the server process  1300 , etc. 
     In some embodiments, the MUTA is implemented as a plurality of text markup language documents, possibly including dynamic contents through server-side scripts or programs, and/or client-side scripts or programs. One illustrative embodiment implements the MUTA as a plurality of JavaServer Pages which dynamically produce HTML-based or JavaScript/ECMAScript-based forms for rendering by the client application  1100 . 
       FIG. 5  depicts a rendered screen display of a step in the MUTA in accordance with this illustrative embodiment. The HTML or JavaScript/ECMAScript forms provide resources for the input of information related to completion of the MUTA. The forms may be rendered by the client application  1100  as illustrated by a first form field  5100 , a second form field  5200 , and a third form field  5300  in  FIG. 5 . In addition, a resource for selection of a deferral action is shown by a ‘defer’ button  5400 . The resource for selection of a deferral action may also be implemented in HTML, a scripting language, or using other Internet programming techniques known in the art. The particular manner of implementation is not fundamental. 
     Again making reference, to  FIG. 3 , the MUTA can be considered to be in, for instance the second state  3200 , when the rendered display of  FIG. 5  is being presented to the user. If the user were to select the deferral action by using a selection device to select the ‘defer’ button  5400 , the deferral transition  3600  would be followed to enter the deferred state  3500 . 
     To further illustrate features of deferred completion of MUTAs, reference can be made to  FIG. 6  where a flow diagram of a ‘deferred completion’ method  6000  in accordance with an illustrative embodiment is shown. The ‘deferred completion’ method  6000  may be carried out by the server process  1300  when engaging in client server communications with the client application  1100 . As depicted in  FIG. 6 , the ‘deferred completion’ method  6000  is shown initiating at an intermediate point in a MUTA. As one of skill in the art will appreciate, the particular steps which come before the ‘deferred completion’ method  6000  in the MUTA are not fundamental and the completion deferral features illustrated by the ‘deferred completion’ method  6000  could be added to conventional transacting systems. 
     Process flow initiates at a ‘start’ terminal  6100  and continues to a ‘generate next transaction page’ process  6200 . The ‘generate next transaction page’ process  6200  involves the server process  1300  creating the next in a series of pages implementing the information flow of the MUTA. This may occur in any conventional manner. In preferred versions of the invention, a server-side programming architecture, such as JavaServer Pages, is used and pages with application logic interact with the server process  1300  to create the contents of the next page dynamically. 
     Process flow continues to a ‘provide next transaction page’ process  6300  in which the server process  1300  transmits the next page from the ‘generate next transaction page’ process  6200  to the client application  1100 . The client application  1100  parses and renders the next page and awaits user interaction. As noted in connection with  FIG. 5 , the user may enter data in form fields or interact with information interchange aspects of the MUTA. In addition, the user may elect deferred completion of the MUTA. The user then responds to the next page; the server process  1300  receives a ‘user response’ data block  6350 , and process flow continues to a ‘deferral’ decision process  6400 . 
     The ‘deferral’ decision process  6400  examines the ‘user response’ data block  6350  to determine if the user has elected deferred completion. If so, process flow continues to an ‘state object setup’ process  6500  which creates a state object similar to, for instance the first transaction state object  4200 . The ‘state object setup’ process  6500  then stores in the state object a transaction identifier, data fields and values necessary for completion of the MUTA, and an identifier of the current position in the MUTA. The data fields and values stored in the state object preferably comprise all data fields and values necessary to complete the MUTA that have been entered by the user up to this point. In addition if sufficient values for data fields that are necessary to complete the MUTA are available without user input, for instance from a record of a previous interaction, these data fields and values are also stored in the state object. 
     Process flow continues to a ‘provide resumption object’ process  6600  that creates and provides to the user an object that will allow the user to resume the MUTA they have deferred. In some embodiments, the resumption object is a URI that identifies a resumption resource. When a request is made to the resumption resource, the data fields and values stored in the state objected would be retrieved and the request is redirected to the position stored in the state object. One skilled in the art will appreciate many other similar implementations where the redirection is to a URI functionally equivalent as to the position stored in the state object. In some embodiments, the URI that identifies the resumption resource could be emailed to the user. 
     In other embodiments, the resumption resource is the resource referenced by the position stored in the state object. In these embodiments, the resumption object could then be the resumption resource. The resumption object could be provided to the user through email or other messaging system. 
     In still other embodiments, the server process  1300  could be configured to provide a page showing a list of the transactions the user has deferred and a resumption resource for each of the list of transactions. The resumption object could be a URI that is emailed to the user that would provide the page when the user&#39;s client application requested the URI. In a variation, the server process could generate the page and the page could be emailed to the user. 
     Numerous other variations will be apparent to one skilled in the art that are within the scope and spirit of the invention. From the ‘provide resumption object’ process  6600 , process flow completes through an ‘end’ terminal  6800 . 
     If the user does not elect to defer completion, the ‘deferral’ decision process  6400  exits through its ‘no’ branch and process flow continues to a ‘complete’ decision process  6700  that determines if steps remain in the MUTA. If so, the ‘complete’ decision process  6700  exits through its ‘yes’ branch and process flow returns to the ‘generate next transaction page’ process  6200  for another iteration. 
     When no steps remain in the MUTA, the ‘complete’ decision process  6700  exits through its ‘yes’ branch and process flow completes through the ‘end’ terminal  6800 . 
     As described with reference to  FIG. 5  and  FIG. 6 , when the user selects to defer completion through a selectable deferral action resource, for instance the ‘defer’ button  5400 , a state object was created to store the state of the MUTA so the user could later complete it. In other variations, a state object is maintained throughout the MUTA so that that user need not affirmatively elect to defer completion. Rather, if the user simply fails to complete the MUTA for any reason, it may be completed by resuming at a later time. 
       FIG. 7  depicts a flow diagram of a ‘deferred completion with automatic state saving’ method  7000  in accordance with an illustrative embodiment. In  FIG. 7  initial steps of a MUTA (which were omitted in  FIG. 6 ) are shown. Process flow initiates at a ‘start’ terminal  7100  and continues when the server process  1300  receives an ‘initiating request’ data block  7200  from the client application  1100  of a user. The ‘initiating request’ data block  7200  in preferred embodiments is an HTTP Request Message for a resource which initiates a MUTA. 
     Process flow continues to a ‘state object setup’ process  7300  that creates a state object such as the first transaction state object  4200  and sets a transaction identifier, a position identifier, and any data field/value pairs that may be available. Processing continues to a ‘generate next transaction page’ process  7400  and a ‘provide next transaction page’ process  7500  that executes analogously to the corresponding processes described in connection with  FIG. 6 . 
     Next, a timeout timer  7600  executing on the server process  1300  awaits a response from the client application  1100 . If no response arrives within a predetermined time period, the timeout timer  7600  exits through its ‘automatic deferral’ branch and process flow continues to a ‘provide resumption object’ process  7850  that executes analogously to the corresponding processes described in connection with  FIG. 6 . Process flow then completes through an ‘end’ terminal  7950 . In some embodiments, the timeout timer  7600  (or other process) could also be configured to insure that the user&#39;s state is saved should an exceptional event force interruption of the MUTA session. For instance, should the server process  1300  crash or otherwise fail in a manner forcing interruption of the session with the client application  1100 , rather than simply exit, the state of the MUTA could then be saved enabling the user to resume from that point. 
     If a response is received from the client application  1100  within the predetermined time period, the timeout timer  7600  exits through its ‘timely response’ branch and data from a ‘user response’ data block  7700  is processed. Next a ‘state object update’ process  7800  updates the state object created by the ‘state object setup’ process  7300 : the position identifier is altered to reflect that the MUTA has advanced a step, and data received in the ‘user response’ data block  7700  is added to the data fields/values. Process flow continues to a ‘complete’ decision process  7900  that executes analogously to the corresponding processes described in connection with  FIG. 6  and process flow either returns to the ‘generate next transaction page’ process  7400  for another iteration or completes through the ‘end’ terminal  7950 . 
     A user should be able to resume a previously deferred MUTA to complete it.  FIG. 8  depicts a flow diagram of a ‘MUTA resumption’ method  8000  in accordance with an illustrative embodiment. The ‘MUTA resumption’ method  8000  is carried out by the server process  1300 . Process flow initiates at a ‘start’ terminal  8100  and continues to receive a ‘resumption URI request’ data block  8200  from the client application  1100  of the user. 
     As described with reference to the ‘provide resumption object’ process  6600 , the user is provided an identifier of a resumption resource in a resumption object. In this illustrative embodiment, the resumption object comprises a resumption resource in the form of a URI in the ‘resumption URI request’ data block  8200 . In preferred embodiments the ‘resumption URI request’ data block  8200  is an HTTP Request Message and the server process  1300  parses the Request Message; extracts the resumption URI; and maps the resumption URI to an internal resource used to access the state object associated with the MUTA. For instance, the mapping may be to a table lookup operation or database query depending, for instance, on the storage architecture for state objects. 
     Process flow continues to a ‘retrieve position’ process  8300  and a ‘retrieve fields/values’ process  8400 . In the ‘retrieve position’ process  8300 , the server process  1300  accesses the state object and retrieves the position identifier from the state object. Similarly, in the ‘retrieve fields/values’ process  8400 , the server process  1300  retrieves the data field/value pairs from the state object. 
     During the period between when a MUTA is deferred and when it is resumed, additional information required to complete the MUTA may have been entered by the user or otherwise made available to the server process  1300 . The additional information could be stored in a user profile. When the user resumes the MUTA after deferral, a ‘merge profile information’ process  8500  examines the user profile to determine what information in the user profile could be used in completion of the remainder of the user transaction application. 
     Process flow continues to a ‘redirect to position’ process  8700  process where the server process  1300  redirects the Request Message from the ‘resumption URI request’ data block  8200  to the position identifier retrieved from the state object by the ‘retrieve position’ process  8300 . Next, a ‘transaction completion’ process  8800  allows the user to complete the MUTA. The ‘transaction completion’ process  8800  may, for instance, be to return to processing such as that described above in connection with  FIG. 6 . Process flow completes through a ‘end’ terminal  8900 .
