Abstract

Aspects of the present invention provide systems and methods for deferred resolution of hypertext links. A web page or other network page may contain tags used to select links to other pages. In an exemplary embodiment of the present invention, a network server evaluates tags selected by a user and may selectively defer following selected links. The deferred links may then be displayed and selectively followed by the user.

Additional aspects of the present invention provide systems and methods for using cell based computational units to evaluate tags selected by a user and selectively defer the requested actions. In an exemplary embodiment, a thread of execution may be initiated on a server for each deferred action and then be suspended using multi-processing techniques. The threads may then be selectively reactivated to initiate the deferred actions.

Claims

1. A server system for providing data to a client system across a communications network, the server system comprising:

means for providing a first tag representative of a desired action to the client system;

means for providing a first link in association with the first tag such that the client system asserts a first signal addressed to the server system on the communications network when the first tag is selected;

wherein the first tag and the first link are configured to be processed by the client system in a manner indistinguishable as to whether the desired action is immediate or deferred;

means for receiving the first signal;

means, in response to the receipt of the first signal, for determining whether the desired action should be deferred; and

means for indicating that the first tag has been selected and that the desired action has been deferred.

2. The server system according to claim 1, further comprising:

means for providing a second tag to the client system;

means for providing a second link in association with the second tag such that the client system asserts a second signal addressed to the server system on the communications network when the second tag is selected;

means for receiving the second signal;

means, in response to the receipt of the second signal, for determining whether the first tag has been previously selected and whether the desired action has been deferred; and

means for executing the desired action in the event that the first tag has been previously selected and the desired action has been deferred.

3. The server system according to claim 2, wherein the desired action includes requesting desired data from a second server system and wherein the means for executing the desired action includes means for asserting a request for the data on the communications network for the desired data to be returned to the client system.

4. The server system according to claim 3, wherein:

the means for providing the first and the second tags includes means for sending hypertext markup language (HTML) to the client system;

the client system includes HTML web browsing software;

the first signal and the second signal comprise universal resource locators (URLs) which each include a file name;

the means for determining whether the desired action should be deferred includes;

a list of file names which are associated with deferred actions and means for comparing the file name in the URL for the first signal to the file names in the list; and

the means for asserting a request for the data on the communications network comprises asserting a hypertext transfer protocol command on the communications network using a return address for the client system such that the desired data is returned to the client system.

5. The server system according to claim 4, wherein the file name in the first signal represents a non-existent file.

6. The server system according to claim 4, further comprising means for maintaining synchronization with web pages displayed by the HTML web browsing software.

7. The server system according to claim 6, wherein the means for maintaining synchronization includes embedding a command in each page of HTML provided by the server system such that the command causes a synchronization signal to be sent to the server system when the page is displayed by the HTML web browsing software.

8. A server system for providing data to a client system across a communications network, the server system comprising:

means for providing a structured publication to the client system;

wherein the structured publication includes at least one tag representative of a desired action which is outside the context of the structured publication;

means for providing a first link in association with the first tag such that the client system asserts a first signal addressed to the server system on the communications network when the first tag is selected;

means for receiving the first signal;

means, in response to the receipt of the first signal, for determining whether the desired action should be deferred;

means for suspending the desired action;

means for receiving an indication that the context of the structured publication is completed; and

means, in response to such indication, for activating the desired action which had been suspended.

9. The server system according to claim 8, wherein the desired action includes requesting desired data from a second server system and wherein the means for executing the desired action includes means for asserting a request for the data on the communications network for the desired data to be returned to the client system.

10. The server system according to claim 9, wherein:

the means for providing the first tag includes means for sending hypertext markup language (HTML) to the client system;

the client system includes HTML web browsing software;

the first signal comprises a universal resource locator (URL) which includes a file name;

the means for determining whether the desired action should be deferred includes;

a list of file names which are associated with deferred actions and means for comparing the file name in the URL for the first signal to the file names in the list; and

the means for asserting a request for the data on the communications network comprises asserting a hypertext transfer protocol command on the communications network using a return address for the client system such that the desired data is returned to the client system.

11. The server system according to claim 10, wherein the file name in the first signal represents a non-existent file.

12. The server system according to claim 10, further comprising means for maintaining synchronization with web pages displayed by the HTML web browsing software.

13. A method for providing data to a client system across a communications network, comprising the steps of:

providing a first tag representative of a desired action to the client system;

providing a first link in association with the first tag such that the client system asserts a first signal addressed to the server system on the communications network when the first tag is selected;

wherein the first tag and the first link are configured to be processed by the client system in a manner indistinguishable as to whether the desired action is immediate or deferred;

receiving the first signal;

in response to the receipt of the first signal, determining whether the desired action should be deferred; and

indicating that the first tag has been selected and that the desired action has been deferred.

14. The method of claim 13, wherein the desired action includes requesting desired data from a second server system and wherein the step of activating the desired action further comprises asserting a request for the data on the communications network for the desired data to be returned to the client system.

15. The method of claim 14, wherein:

the step of providing the first tag further comprises sending hypertext markup language (HTML) to the client system;

the client system includes HTML web browsing software;

the first signal comprises a universal resource locator (URL) which includes a file name;

the step of determining whether the desired action should be deferred further comprise;

associating a list of file names with deferred actions and comparing the file name in the URL for the first signal to the file names in the list; and

the step of asserting a request for the data on the communications network further comprises asserting a hypertext transfer protocol command on the communications network using a return address for the client system such that the desired data is returned to the client system.

16. A method according to claim 15, wherein the file name in the first signal represents a non-existent file.

17. A method according to claim 15, further comprising the step of maintaining synchronization with web pages displayed by the HTML web browsing software.

18. A method for providing data to a client system across a communications network, comprising the steps of:
