The method also includes displaying, by the IHS, the particular webpage in response to receiving the request to display the particular webpage. The method further includes intercepting, by the browser of the IHS, a request to navigate away from the particular webpage to a target webpage. The method still further includes determining, by the browser of the IHS, whether to grant or block the request to navigate away from the particular webpage to the target webpage. The browser provides a block decision if navigating away from the particular webpage would cause loss of information of the particular webpage. Alternatively, the browser provides a grant decision if navigating away from the particular webpage would not cause loss of information of the particular webpage. The method also includes halting, by the browser, navigation away from the particular webpage in response to the block decision.
In another embodiment, an information handling system (IHS) is disclosed that includes a processor and a memory coupled to the processor. The memory stores a browser that is configured to receive a request to display a particular webpage. The browser is also configured to display the particular webpage in response to receiving the request to display the particular webpage. The browser is further configured to intercept a request to navigate away from the particular webpage to a target webpage. The browser is still further configured to determine whether to grant or block the request to navigate away from the particular webpage to the target webpage. The browser provides a block decision if navigating away from the particular webpage would cause loss of information of the particular webpage. Alternatively, the browser provides a grant decision if navigating away from the particular webpage would not cause loss of information of the particular webpage. The browser is also configured to halt navigation away from the particular webpage in response to the block decision.
In still another embodiment, a browser computer program product is disclosed that includes a computer readable storage medium. The browser includes first program instructions that receive a request for an information handling system (IHS) to display a particular webpage. The browser also includes second program instructions that instruct the IHS to display the particular webpage in response to receiving the request to display the particular webpage. The browser further includes third program instructions that intercept a request to navigate away from the particular webpage to a target webpage. The browser still further includes fourth program instructions that determine whether to grant or block the request to navigate away from the particular webpage to the target webpage. The fourth program instructions provide a block decision if navigating away from the particular webpage would cause loss of information of the particular webpage. Alternatively, the fourth program instructions provide a grant decision if navigating away from the particular webpage would not cause loss of information of the particular webpage. The browser also includes fifth program instructions that halt navigation away from the particular webpage in response to the block decision. The first, second, third, fourth and fifth program instructions are stored on the computer readable storage medium.

DETAILED DESCRIPTION
The disclosed information handling system (IHS) includes a browser with a locking tool that controls navigation away from a particular webpage such as a currently displayed webpage. The user selects a webpage lock in the locking tool to enable the locking feature of the locking tool. The locking tool monitors for, and intercepts, a request to navigate away from the particular webpage. The locking tool of the browser determines whether to grant or block a request to navigate away from the particular webpage. If navigation away from the particular webpage, such as the currently displayed webpage, will result in a loss of information, then the locking tool of the browser prevents or blocks navigation away from the particular webpage. However, if navigation away from the particular webpage will not result in a loss of information, then the locking tool of the browser does not prevent or block navigation away from the particular webpage.
In one embodiment, the locking tool intercepts requests, i.e. commands, to navigate away from the particular webpage including: browser webpage direction controls (e.g. forward, backward, refresh, home buttons), hyperlinks, bookmarks, hotkeys, and page close requests. The locking tool may be a built-in function of the browser or an add-on (e.g. plugin) to the browser.
FIG. 1 is a block diagram of an information handling system (IHS) 100 that employs the disclosed browser locking tool methodology to prevent undesired navigation away from a particular webpage. IHS 100 includes a processor 105 that may include multiple cores. IHS 100 processes, transfers, communicates, modifies, stores or otherwise handles information in digital form, analog form or other form. IHS 100 includes a bus 110 that couples processor 105 to memory 115 via a memory controller 120 and memory bus 125. System memory 115 may also be referred to as main memory. System memory 115 may be a static random access memory (SRAM) array or a dynamic random access memory (DRAM) array. Processor 105 may also include local memory such as L1, L2 and L3 caches. A video graphics controller 130 couples display 135 to bus 110. Nonvolatile storage 140, such as a hard disk drive, CD drive, DVD drive, or other nonvolatile storage couples to bus 110 to provide IHS 100 with permanent storage of information. System memory 115 and nonvolatile storage 140 are both forms of memory stores. Nonvolatile storage 140 stores an operating system 145 (OPERATING SYS) that governs operation of IHS 100. I/O devices 150, such as a keyboard and a pointing device, couple to bus 110 via I/O controller 155 and I/O bus 160.
One or more expansion busses 165, such as USB, IEEE 1394 bus, ATA, SATA, PCI, PCIE, DVI, HDMI and other busses, couple to bus 110 to facilitate the connection of peripherals and devices to IHS 100. A network interface controller 170 couples to bus 110 to enable IHS 100 to connect by wire or wirelessly to a network and other information handling systems. Network interface controller 170 may also be called a network communication adapter or a network adapter. While FIG. 1 shows one IHS that employs processor 105, the IHS may take many forms. For example, IHS 100 may take the form of a desktop, server, portable, laptop, notebook, tablet, or other form factor computer or data processing system. IHS 100 may take other form factors such as a gaming device, a personal digital assistant (PDA), a portable telephone device, a communication device or other devices that include a processor and memory.
IHS 100 includes a browser locking tool computer program product 600 on digital media 175 such as a CD, DVD or other media. For simplicity, the term browser locking tool will be used below. In one embodiment, browser locking tool 600 is within browser 200 as shown in FIG. 1. Browser locking tool 600 may also be an add-in that the user or other entity installs in IHS 100 at the user's convenience. In actual practice, IHS 100 may store browser 200 and browser locking tool 600 in nonvolatile storage 140 as browser 200′ and browser locking tool 600′. IHS 100 may also store operating system 145 (OPERATING SYS) in nonvolatile storage 140. When IHS 100 initializes, the IHS loads operating system 145 into system memory 115 for execution as operating system 145′. IHS 100 also loads browser 200′ and browser locking tool 600′ into system memory 115 for execution as browser 200′′ and browser locking tool 600′′, respectively.
FIG. 2 shows the browser as browser window 200 that IHS 100 may display on display 135 when executing browser locking tool 600. More particularly, FIG. 2 illustrates a scenario wherein the browser locking tool 600 is disabled. To instruct browser locking tool 600 to assume the disabled state, the user or other entity selects lock button 205 using an I/O device 150, for example, a pointing device. When the user so selects lock button 205, the lock icon that represents lock button 205 changes from a closed lock (not shown in FIG. 2) to an open lock (as shown in FIG. 2).
Browser window 200 may display two types of navigation controls: browser level navigation controls and webpage level navigation controls. Browser level navigation controls control navigation globally at the browser level, namely for the entire browser. For example, browser level navigation controls may include a backward button 210, forward button 215, refresh button 220, home button 225, uniform resource locator (URL) field 230, browser window close button 235, bookmark 240-1, bookmark 240-2, bookmark 240-3, . . . bookmark 240-N wherein N is the total number of bookmarks displayed. Webpage level navigation controls control navigation at the webpage level, namely within a webpage. For example, webpage level navigation controls may include form submit button 245, form reset button 250, hyperlink 255-1, hyperlink 255-2, hyperlink 255-3, . . . hyperlink 255-M wherein M is the total number of hyperlinks displayed. These three button types, namely “submit”, “reset” and “hyperlink”, correspond to webpage level navigation commands.
Browser window 200 may display a particular webpage 260 within browser window 200. URL field 230 displays the address of that particular webpage 260. The address of a particular webpage 260 may include a domain. In one embodiment, a particular webpage is part of a particular website if the domain is the same. In other words, if two webpages exhibit the same domain, then they are part of the same website. To instruct URL field 230 to navigate to another webpage, the user or other entity may select URL field 230 and input an address using an I/O device 150, such as a keyboard.
The user or other entity may navigate to multiple particular webpages. Browser 200 stores a list (not shown) of previously accessed webpages. Entries in the list of previously accessed webpages may exhibit temporal ordering with the most recently accessed webpage at the top of the list. To instruct backward button 210 to navigate down the list of previously accessed webpages, the user or other entity may select backward button 210. If the list of previously accessed webpages does not contain any entries below the current webpage, navigation does not occur. To instruct forward button 215 to navigate up the list of previously accessed webpages, the user or other entity may select forward button 215. If the list of previously accessed webpages does not contain any entries above the current webpage, navigation does not occur. To instruct refresh button 220 to reload the current webpage, the user or other entity may select refresh button 220. If the user or other entity utilizes any navigation control other than backward button 210, forward button 215, or refresh button 220, all entries stored above the current webpage entry in the list of previously accessed webpages are lost. The browser navigates to the webpage and appends the now current webpage to the top of the list of previously accessed webpages. For example, if the user or other entity clicks backward button 210, there will be one webpage above the current webpage in the list of previously accessed webpages. If the user or other entity navigates to a new webpage by selecting URL field 230 and entering an address into URL field 230, the webpage to which the user or entity could have previously navigated by selecting forward button 215 has been removed from the list. After navigation, the browser displays the current webpage to which the user or entity navigated using URL field 230. The browser 200 appends the now current webpage to the top of the list of previously accessed webpages. The original webpage with which the user or entity started in this example is now lost. Refreshing a particular webpage such as the currently displayed webpage is a form of navigating away from the particular web page, because such refreshing may result in displaying an altered web page that is not the same as the particular web page. In other words, information may be lost when such refreshing occurs.
The browser 200 may store the address of a home webpage as set by the user or other entity. To instruct the home button 225 to navigate to the home webpage, the user or other entity selects home button 225. The browser 200 may store the addresses of webpage that a user or other entity selects as bookmark 240-1, bookmark 240-2, bookmark 240-3, . . . bookmark 240-N wherein N is the total number of bookmarks. To instruct bookmark 240-1, bookmark 240-2, bookmark 240-3, . . . bookmark 240-N, wherein N is the total number of bookmarks, to navigate to a particular webpage, the user or other entity selects bookmark 240-1, bookmark 240-2, bookmark 240-3, . . . bookmark 240-N, respectively.
To instruct browser window close button 235 to close browser window 200, the user or other entity selects browser window close button 235. The browser may lose information when the browser closes. The user or other entity may select any control or function described herein by the use of a hotkey.
A particular webpage 260, such as a currently displayed webpage, may include hyperlinks to navigate to other webpages. Hyperlinks may take the form of any element in a webpage. In one embodiment, hyperlink 255-1 could be text. In another embodiment, hyperlink 255-2 could be an image. To instruct hyperlink 255-1, hyperlink 255-2, hyperlink 255-3, . . . hyperlink 255-M, wherein M is the total number of hyperlinks, to navigate to a particular webpage, a user or other entity selects hyperlink 255-1, hyperlink 255-2, hyperlink 255-3, . . . hyperlink 255-M, respectively, wherein M is the total number of hyperlinks.
A particular webpage 260, namely a currently displayed webpage, within browser window 200 may include form elements. To instruct form submit button 245 to submit form information and navigate to a webpage, the user or entity selects form submit button 245. To instruct form reset button 250 to clear form information and navigate back to the currently displayed webpage, the user or entity selects form reset button 250. A particular webpage 260 may include a customer form. The customer form may include a form name field 265, form address field 270, form city field 275, and form state field 280. The user or other entity may input name, address, city, and state text data to each field, respectively. The blank form name field 265, form address field 270, form city field 275, and form state field 280 in FIG. 2 represent a form after a loss of data. In addition to form information that may be lost, other information such as session information or still other information that may be hidden from the user, may also be lost when the user navigates away from the currently displayed webpage to a target webpage.
FIG. 3 includes many elements in common with FIG. 2. When comparing FIG. 3 with FIG. 2, like numbers indicate like elements. FIG. 3 illustrates a scenario wherein the browser locking tool 600 of browser 200 is enabled. To instruct browser locking tool 600 to assume the enabled state, the user or other entity selects lock button 305. When the user so selects lock button 305, the lock icon that represents lock button 305 changes from an open lock (not shown in FIG. 3) to a closed lock (as shown in FIG. 3).
A particular webpage 360 within browser window 300 may include form elements. The customer form may include a form name field 365, form address field 370, form city field 375, and form state field 380. The user or other entity may input form information such as name, address, city, and state text data to each field, respectively. The form name field 365, form address field 370, form city field 375, and form state field 380 represent a form after the user or other entity provides form information to the form fields. In one embodiment, the browser locking tool 600 prevents navigation away from a particular webpage by default settings, i.e. user preferences. User preferences may define, for example, that the form submit button 345 and form refresh button 350 may not prevent navigation. In another embodiment, the browser locking tool 600 prevents navigation away from a particular webpage unless the user or other entity selects a webpage level navigation control by default settings, i.e. user preferences. In yet another embodiment, the browser locking tool 600 prevents navigation away from a particular webpage and in so doing generates a dialog box prompting the user or other entity with a warning and option to proceed, as described in more detail below. The browser locking tool 600 may employ some or all of the described proposed embodiments of the browser locking tool 600 on a per website or per webpage basis as configured by the user or other entity in the user preferences. In contrast, if the user or other entity does not enable the browser locking tool 600 by selection or default, the form data as described above, as well as other webpage data, may be lost.
FIG. 4 includes many elements in common with FIG. 3. When comparing FIG. 4 with FIG. 3, like numbers indicate like elements. FIG. 4 illustrates a scenario wherein the browser locking tool 600 is enabled. To instruct browser locking tool 600 to assume the enabled state, the user or other entity selects lock button 405. When the user so selects lock button 405, the lock icon that represents lock button 405 changes from an open lock (not shown in FIG. 4) to a closed lock (as shown in FIG. 4). The user or other entity may create a tab 485-1, tab 485-2, . . . tab 485-L where L is the number of tabs that the user creates. When a user or other entity selects one of tab 485-1, tab 485-2, . . . tab 485-L, the browser 200 in response may display a particular respective webpage 460. As shown in FIG. 4, tab 485-1 is the active tab. The particular webpage 460 and URL field 430 display the webpage and address associated with active tab 485-1, respectively. Browser window 400 does not display the webpage and address associated with tab 485-2, . . . tab 485-L, because the those tabs are not the active tab, i.e. not the currently selected tab.
Lock button 490-1, lock button 490-2, . . . lock button 490-L, function similarly to lock button 405, but instead provide locking on a tab by tab basis for tab 485-1, tab 485-2, . . . tab 485-L, instead of the locking the entire browser window 400. In other words, in one embodiment, the state of lock button 490-1 only applies to tab 485-1. In one embodiment, when the user or other entity creates tab 485-1, tab 485-2, . . . tab 485-L, then lock button 490-1, lock button 490-2, . . . lock button 490-L inherit their respective states from the current state of lock button 405. For example, when the user or other entity creates tab 485-1, the browser sets lock button 490-1 to the locked state because lock button 405 is set to the locked state. The user or entity may change the state of any lock button by selecting the respective lock button. When the user or other entity selects lock button 490-2, the lock icon that represents lock button 490-2 changes from a closed lock (not shown in FIG. 4) to an open lock (as shown in FIG. 4). Depending on the state of the lock button 490-1, lock button 490-2, . . . lock button 490-L, browser locking tool 600 controls the locking of navigation via tab 485-1, tab 485-2, . . . tab 485-L, respectively, as described above for browser window 200 and browser window 300.
To instruct tab close button 495-1, tab close button 495-2, . . . tab close button 495-L to close tab 485-1, tab 485-2, . . . tab 485-L, where L is the number of tabs, respectively, the user or other entity selects tab close button 495-1, tab close button 495-2, . . . tab close button 495-L, respectively. A tab may lose information when the tab closes. If browser locking tool 600 controls tab 485-1, tab 485-2, . . . tab 485-L, browser locking tool 600 will handle tab 485-1, tab 485-2, . . . tab 485-L as described above for browser window 300. To instruct browser window close button 435 to close browser window 400, the user or other entity selects browser window close button 435. If browser locking tool 600 does not control tab 485-1, tab 485-2, . . . tab 485-L, then tab 485-1, tab 485-2, . . . tab 485-L may lose information when browser window 400 closes, because tab 485-1, tab 485-2, . . . tab 485-L will also close. However, If browser locking tool 600 controls tab 485-1, tab 485-2, . . . tab 485-L, browser locking tool 600 will handle tab 485-1, tab 485-2, . . . tab 485-L as described above for browser window 300. In other words, if any tab is locked, the browser will not close that tab.
In one embodiment, the browser locking tool 600 may create a warning dialog box 500, as seen in FIG. 5. Browser locking tool 600 may cause display of the warning dialog box 500 when the current webpage is protected by the browser locking tool 600 and the current user or other entity attempts to navigate to another webpage. The warning dialog box 500 may present the user or other entity with several choices with respect to how to proceed when the user or other entity attempts to navigate to a webpage when the current webpage is in the locked state.
The user or entity may choose to select cancel button 510 to remove dialog box 500 and leave the current webpage unchanged. The user or entity may choose to select disable and continue button 505 to remove warning dialog box 500, to disable the browser locking tool 600 on the current webpage and navigate to the webpage that the attempted navigation request targets. The user or entity may choose to select “open in a new window” button 515 to remove dialog box 500 and open the attempted navigation request in a new browser window. The user or entity may choose to select “open in a new tab” button 520 to remove dialog box 500 and open the attempted navigation request in a new tab, in the same browser as the current webpage.
FIG. 6A is a flowchart that shows one embodiment of the disclosed browser locking tool method 600. Process flow begins when the user or other entity activates the browser, as per start block 602. The user or other entity may attempt to navigate to a target webpage that is different from the currently displayed webpage, as per block 604. The user or other entity may select to enable or disable the navigation blocking feature of browser locking tool 600 by toggling lock button 205, lock button 305, lock button 405. When employing browser tabs such as tab 485-1, tab 485-2, . . . tab 485-L, the user or other entity may enable or disable the navigation blocking feature of such tabs by toggling, lock button 490-1, lock button 490-2, lock button 490-L, respectively, as per block 606.
Browser locking tool 600 performs a test to determine if the user selected browser webpage direction control, for example one of backward button 310, forward button 315 and refresh button 320, as per decision block 608. If browser locking tool 600 determines that the user selected a browser webpage direction control, then browser locking tool 600 intercepts the selection of the webpage direction control and displays a warning dialog box 500, as per block 610. Browser locking tool 600 determines if the user inputs a disable command in response to warning dialog box 500, as per decision block 612. If browser locking tool 600 determines that user did not input a disable command, then process flow continues back to decision block 608. However, if browser locking tool 600 determines that the user did input a disable command, then the browser locking tool 600 allows the browser to navigate to the target webpage, as per block 614. The browser locking tool 600 disables the navigation blocking feature of browser locking tool 600, as per block 616. Process flow ends at block 618 with the disabling of browser locking tool 600.
However, if browser locking tool 600 determines at decision block 608 determines that the user or other entity did not select a webpage browser direction control, then browser locking tool 600 performs a test to determine if the user selected a webpage level navigation control, as per block 620. If browser locking tool 600 determines that the user or other entity selects a webpage navigation control, the browser locking tool 600 checks to determine if user preferences are set, as per block 622 (in FIG. 6B). If user preferences are not set, i.e. default settings, the blocking feature of the browser locking tool 600 denies webpage navigation and process flow continues at block 608, as per block 624.
However, if decision block 622 determines that user preferences are set, i.e. not default settings, the browser locking tool tests to determine if the navigation request is to a target webpage that is part of the same website as the currently displayed webpage, as per block 626. If the browser locking tool 600 determines that the target webpage belongs to the same website as the currently displayed webpage, then browser locking tool 600 checks the user preferences to determine if the user or other entity specified if webpage navigation within the same website is allowed, as per block 628. If the user preferences allow same website navigation, then the browser locking tool 600 allows navigation to the target webpage and the process flow continues at block 608, as per block 630.
However, if decision block 626 determines that the target webpage is not in the same website as the currently displayed website, or if decision block 626 determines that the target webpage is in the same website as the currently displayed webpage and decision block 628 determines that the user preferences are not set to allow the browser locking tool 600 to navigate to webpages in the same website, then browser locking tool 600 may display a modified warning dialog box 500, as per block 632. The modified warning dialog box 500 may replace the disable and continue 505 button with a continue button. The continue button allows navigation to the target webpage away from the currently displayed webpage when the target webpage is in the same website, e.g. same domain, as the currently displayed website, but does not disable browser locking tool 600. The user or other entity may select to allow the blocking feature of browser locking tool 600 to temporarily allow navigation, as per block 634. If the user or other entity allows same website navigation, the browser locking tool 600 allows navigation to the target webpage, as per block 630, and process flow continues to block 608. However, if decision block 634 determines that the blocking feature of browser locking tool 600 may not navigate to the target webpage, then browser locking tool 600 does not navigate to the target webpage, as per block 624, and process flow continues at block 608.
Returning to FIG. 6A, if decision block 608 determines that user or other entity did not select webpage browser direction control, and if decision block 620 determines that the user or other entity did not select a webpage navigation control, then browser locking tool 600 performs a test to determine if the user selected a browser link, such as home button 325, URL field 330, bookmark 340-1, bookmark 340-2, bookmark 340-3, . . . bookmark 340-N where N is the total number of bookmarks, as per block 636. If browser locking tool 600 determines that the user or other entity selected a browser link, the browser locking tool 600 checks to determine if user preferences are set, as per block 638 of FIG. 6C. If user preferences are not set, i.e. default settings are not set, the blocking feature of the browser locking tool 600 denies webpage navigation, as per block 640 and process flow continues at block 608.
However, if decision block 638 determines that user preferences are set, i.e. not default settings, then browser locking tool 600 may display a warning dialog box 500, as per block 642. The user or other entity may select to allow the locking feature of browser locking tool 600 to allow navigation, as per block 644. If the user or other entity allows navigation, then browser locking tool 600 allows navigation to the target webpage, as per block 614 of FIG. 6A. The browser locking tool 600 disables the navigation locking feature of browser locking tool 600, as per block 616 of FIG. 6A. Process flow ends at block 618 with the disabling of browser locking tool 600. However, if decision block 644 of FIG. 6C determines that the locking feature of browser locking tool 600 may not navigate to the webpage, then browser locking tool 600 does not navigate to the target webpage and process flow continues at block 608, as per block 640.
If decision block 608 of FIG. 6A determines that the user or other entity did not select webpage browser direction control, and if decision block 620 determines that the user or other entity did not select a webpage navigation control, and if decision block 636 determines that the user or other entity did not select a browser link, then browser locking tool 600 performs a test to determine if the user selects a webpage close function, such as browser window close button 335, tab close button 495-1, tab close button 495-2, . . . tab close button 495-L where L is the number of tabs, as per block 646. If browser locking tool 600 determines that the user or other entity selects the webpage close function, then browser locking tool 600 checks to determine if user preferences are set, as per block 648 of FIG. 6D. If user preferences are not set, i.e. default settings, the blocking feature of the browser locking tool 600 denies webpage closure, as per block 650, and process flow continues at block 608 of FIG. 6A.
However, if decision block 648 of FIG. 6D determines that user preferences are set, i.e. the user preferences are not default settings, then browser locking tool 600 may display a modified warning dialog box 500, as per block 652. The modified warning dialog box 500 may replace the disable and continue 505 button with a close button. The close button allows the browser or tab to close the webpage. The browser locking tool 600 performs a test to determine if the user or other entity selects the option to allow the locking feature of the browser or tab to close the currently displayed webpage, as per decision block 654. If the user or other entity selects to allow the browser or tab to close the webpage, then browser locking tool 600 allows such closure, as per block 656, by disabling the navigation locking feature of browser locking tool 600, as per block 616. Process flow ends at block 618 of FIG. 6A with the disabling of browser locking tool 600. However, if decision block 654 of FIG. 6D determines that the locking feature of browser locking tool 600 may not close the webpage, then browser locking tool 600 does not close the webpage, as per block 650, and process flow continues at block 608.
If decision block 608 of FIG. 6A determines that user or other entity did not select webpage browser direction control, and if decision block 620 determines that the user or other entity did not select a webpage navigation control, and if decision block 636 determines that the user or other entity did not select a browser link, and if decision block 646 determines that the user or other entity did not close the webpage, then browser locking tool 600 performs a test to determine if the user selects to disable the blocking feature of browser locking tool 600, such as by selecting lock button 305, lock button 490-1, lock button 490-2, . . . lock button 490-L, as per block 658. If browser locking tool 600 determines at decision block 658 that the user or other entity does not select to disable the blocking feature of browser locking tool 600, then browser locking tool 600 does not unlock the webpage and process flow continues at block 608. However, if decision block 658 determines that the locking feature of browser locking tool 600 may be unlocked, then browser locking tool 600 disables the locking feature of browser locking tool 600, as per block 616. Process flow ends at block 618 with the disabling of browser locking tool 600.
