Also, the use of “a” or “an” is employed to describe elements and components described herein. This is done merely for convenience and to give a general sense of the scope of the invention.
FIG. 1 illustrates a particular embodiment of a system to provide a network-based service. The system 100 includes a user-based reverse proxy server (UBRP) 102 that communicates with an enterprise portal 104. The institutional portal 104 is accessible to a user device 106 via a network, such as the Internet 108 or another local area or wide area network. The UBRP 102 also communicates with an application server, such as the application servers 112 and 114, which can be adapted to provide legacy applications associated with a network-based service.
In a particular illustrative embodiment, the UBRP 102 is adapted to receive a request for a network-based service from the enterprise portal 104. The UBRP 102 can receive the request, for example, from the user device 106 via the Internet 108. The UBRP 102 can be adapted to identify an application associated with the network-based service. In one example, the request can include a user id, such as a user login string, a cookie, another identifier of the user, or any combination thereof, and the UBRP 102 can be adapted to identify the application based on the user id. In another embodiment, the UBRP 102 can be adapted to identify the application based on the requested service, the user id, other information, or any combination thereof.
The UBRP 102 can be adapted to retrieve a user file that includes user data elements related to a user that is associated with the request. The user file can include user data elements related to the user that is associated with the request, another user, or any combination thereof. In one example, the user file can include data elements with a header line or can be in XML format. The user file can be stored at the UBRP 102, or at a data store 110 that is accessible to the UBRP 102.
Further, the UBRP 102 can be adapted to retrieve an action file associated with the identified application. The action file indicates types of user data elements required for users to access the application. The action file can be stored at the UBRP 102 or at the data store 110. The UBRP 102 can be adapted to identify, from the action file, a type of user data element that is required for the user associated with the request to access the application.
The UBRP 102 can be adapted to retrieve the required user data element from the user file and to use the required user data element to create a cookie, a URL, another proxy request element, or any combination thereof, to proxy the request to the identified application. For example, a URL required for a particular user to access the identified application can be “http://www.application1/service12/id=^SSN^,” which can be stored at the UBRP 102 in the action file corresponding to the identified application. The UBRP 102 can be adapted to retrieve a social security number value from the user file and to place the value in the SSN field of the URL. Any number of data fields can be included in the URL.
In another example, a cookie required for a particular user to access the identified application can be “COOKIE name:app1;domain:att.com;path/value=^APPID^,” which can be stored in the action file. The cookie specifies that a cookie named app1 must be set to the requesting user's APPID value from the corresponding user file. The UBRP 102 can be adapted to retrieve the user's APPID and insert it into the cookie before transmitting the created cookie to the identified application.
The UBRP 102 is adapted to proxy the request for the network-based service to the identified application by sending the created proxy request element to an application server associated with the application, such as the application server 112. The UBRP 102 can be adapted to determine whether the user is logged in to the application after proxying the request to the application and to proxy communication between the requesting device and the identified application after the user is logged in. The UBRP 102 can continue proxying communication between the requesting device and the identified application until the user session has ended.
In a particular embodiment, the UBRP 102 can be adapted to receive a request to add a user. The UBRP 102 can add a user data element related to the user to a user file stored at the UBRP 102. Additionally, as a new application is integrated to the system 100, a directory, an action file, or any combination thereof, can be created for the application at the UBRP 102.
In another particular illustrative embodiment, the UBRP 102 can be adapted to receive a request for a network-based service from the enterprise portal 104, where the request includes a URL submitted by the user device 106 to the enterprise portal 104. The UBRP 102 can be adapted to examine a URL included with the request, in order to identify a requested application. For example, the URL https://www.att.com/application1 can be received with a request at the UBRP 102 via the enterprise portal 104. The UBRP 102 can be adapted to identify “application1” as the requested application. Each application can have its own directory.
The UBRP 102 can be adapted to retrieve a user id from a cookie received with the request and to retrieve a user file based on the user id. Further, UBRP 102 can be adapted to open an action file associated with the requested application. The UBRP 102 can be adapted to identify, from the action file, a user data element that is required for the user associated with the request to access the application.
The UBRP 102 can be adapted to retrieve from the user file a user data element that is required for the user associated with the request to access the application. In addition, the UBRP 102 can be adapted to use the required user data element to create another URL including the retrieved user data element. The UBRP 102 can be adapted to redirect the request for the network-based service to the identified application by sending the created URL to an application server associated with the application. The UBRP 102 can be adapted to proxy communication between the requesting device and the application until a session ends.
In a particular embodiment, the UBRP 102 can be adapted to determine an access level for a user associated with the user. For instance, the user may only be allowed to access certain aspects of an application, such as particular information associated with the user, particular functions of the application that are accessible to the user (e.g., an administrator or non-administrator employee of a company), another aspect of the application, or any combination thereof. Other characteristics of a request, such as system views previously granted to the user and specific data elements required by applications can be stored at the UBRP 102. The UBRP 102 can present these characteristics to the application with a proxied request.
In an illustrative, non-limiting embodiment, the UBRP 102 can include hardware, processing logic, such as a processor (not shown), memory (not shown) that includes instructions that are readable and executable by the processing logic, or any combination thereof, to perform one or more functions of the UBRP 102 with respect to providing a network-based service. In one example, the UBRP 102 can include a Java servlet.
FIG. 2 illustrates a particular embodiment of a method of providing a network-based service. At block 200, a UBRP receives a request for a network-based service from an enterprise portal. The request can be received, for example, from a requesting device associated with a user. Moving to block 202, the UBRP identifies an application associated with the network-based service. In one example, the request can include a user id, such as a user login string, a cookie, another identifier of the user, or any combination thereof, and the UBRP can identify the application based on the user id.
Proceeding to block 204, the UBRP retrieves a user file that includes user data elements related to a user that is associated with the request. Continuing to block 206, the UBRP retrieves an action file associated with the identified application. The action file indicates user data elements required for users to access the application. Advancing to block 208, the UBRP identifies from the action file a user data element that is required for the user associated with the request to access the application.
At block 210, the UBRP uses the required user data element to create a cookie, a URL, another proxy request element, or any combination thereof. Moving to block 212, the UBRP proxies the request for the network-based service to the identified application by sending the created proxy request element to an application server associated with the application. Proceeding to decision node 214, the UBRP can determine whether the user is logged in to the application after proxying the request to the application. If the user is not logged in, the method can continue to block 215, and the UBRP can return an error message to the requesting device via the enterprise portal.
Conversely, if the user is logged in, the method can advance to block 216, and the UBRP proxies communication between the requesting device and the identified application. At decision node 218, the UBRP can determine whether a user session has ended. The UBRP can continue proxying communication between the requesting device and the application until the user session has ended. The method terminates at 220.
FIG. 3 is a flow diagram illustrating another particular embodiment of a method of providing a network-based service. At block 300, a request for a network-based service is received from an enterprise portal via a Java servlet at a UBRP. Moving to block 302, the Java servlet examines a URL included with the request to identify a requested application and an access level corresponding to the user for the application. Proceeding to block 304, the Java servlet retrieves a user id from a cookie received with the request. Continuing to block 306, the Java servlet opens an action file associated with the requested application. Advancing to block 308, the Java servlet identifies from the action file a user data element that is required for the user associated with the request to access the application.
At block 310, Java servlet retrieves from the user file a user data element that is required for the user associated with the request to access the application. At block 312, the Java servlet uses the required user data element to create another URL including the retrieved user data element. Moving to block 314, the Java servlet redirects the request for the network-based service to the identified application by sending the created URL to an application server associated with the application. Proceeding to block 316, the Java servlet proxies communication between the requesting device and the application until a session ends. The method terminates at 318.

Accordingly, replacement standards and protocols having the same or similar functions as those disclosed herein are considered equivalents thereof.
In accordance with the embodiments disclosed herein, a system and method to provide a network-based service are provided. Enterprise portals can rely on legacy systems historically used internally within the enterprise. Legacy systems providing the services may be costly to modify, in terms of cost and time, in order to accommodate requests from the enterprise portal. As organizations struggle to bring more services online, a user-based reverse proxy (UBRP) can integrate applications historically considered back-end to the enterprise portal. Classic reverse proxies provide access to services uniformly, such that all users requesting a service access the service in the same manner with the same characteristics. Thus, an enterprise providing a service is often required to vary the service depending on who is making a request.
Seamlessly integrating legacy systems into an enterprise portal with a single sign-in mechanism can improve the user's experience. The enterprise portal typically does not contain data elements required for systems providing services intended for public offering, particularly systems associated with legacy applications historically offered internally. Nonetheless, in order to offer services to a wide population, additional data elements beyond those contained in the original request must often be assembled and presented to the application on behalf of the requesting user. Thus, in order to be effective, a request to an application via an enterprise portal must be combined with other knowledge, such as knowledge of what application is being requested, who is making the request, what system is receiving the request on behalf of the proxy, where the application resides, and what data elements are required to identify the user to the application.
In a particular embodiment, a user-based reverse proxy (UBRP) receives requests for services from an enterprise portal. The UBRP is an expandable, flexible, easily administrable mechanism that permits quickly bringing services online that require user data beyond that which might be housed in the enterprise portal. The UBRP can store knowledge of all supported services, each service's required data elements, a network location for each service (such as a URL for an application server), user data elements for each user, or any combination thereof. Based on a user identifier transmitted with the request for a service, the UBRP can determine the application supporting the service, gather required data element(s) for the application, and can proxy the request from the enterprise portal to the application, using the required data element(s).
In an illustrative embodiment, the UBRP can examine data made with a request in order to determine whether a user has access rights to an application and what access rights the user has. Other characteristics of a request, such as system views previously granted to the user and specific data elements required by applications can be stored at the UBRP. These characteristics can be presented to the application by the UBRP with a proxied request.

13. The system of claim 12, wherein the request for the service is received at the user-based reverse proxy device from an enterprise portal.

14. The system of claim 12, wherein the user-based reverse proxy is accessible to the user over the internet via the enterprise portal.

15. The system of claim 12, wherein the operations further comprise proxying the communication between the requesting device associated with the user and the application after the application has granted access to the user.

16. A non-transitory computer-readable medium including processor-readable instructions that are executable by a processor to perform operations, the operations comprising:
receiving a request for a service at a proxy server, wherein the request includes identity information to identify a user, wherein the request includes a first uniform resource locator;
identifying an application associated with the service based on the identity information and the first uniform resource locator, wherein the application is identified from a portion of an address of the first uniform resource locator;
retrieving an action file stored at the proxy server, the action file identifying a type of user data element required by the application for the user to access the application;
retrieving the user data element stored at the proxy server;
creating, by utilizing the identified user data element, an application request element and a second uniform resource utilized for proxying the request for the service, wherein the application request element includes the identified user data element and the second uniform resource locator utilized, wherein the identified user data element is inserted into the second uniform resource locator, wherein the second uniform resource locator is different from the first uniform resource locator;
proxying the request to the application using the created application request element and the second uniform resource locator, wherein the request that is proxied includes system views granted to the user, an identification of a location that the application resides, and an identification of information required to identify the user to the application;
determining whether the user is logged into the application after proxying the request to the application;
returning an error message to a requesting device associated with the user when the user is determined to not be logged into the application; and
proxying a communication between the requesting device and the application when the user is determined to be logged into the application.
