Abstract

A method, system and apparatus for time-out management for session-dependent applications. A time-out management system can include one or more of pages defining a session-dependent application. The system further can include a server-side time-out manager configured for use in a content server in detecting a time-out condition in the session-dependent application when the session-dependent application has been distributed to a content client. Finally, the system can include at least one client-side time-out manager configured to detect activity for the session-dependent application and to notify the content server when activity is detected in the session-dependent application when the session-dependent application has been distributed to the content client.

Claims

1. A time-out management system comprising:

a plurality of pages defining a session-dependent application;

a server-side time-out manager configured for use in a content server in detecting a time-out condition in said session-dependent application when said session-dependent application has been distributed to a content client; and

,

at least one client-side time-out manager configured to detect activity for said session-dependent application and to notify said content server when activity is detected in said session-dependent application when said session-dependent application has been distributed to said content client.

2. The system of claim 1, wherein said at least one client-side time-out manager is configured for distribution to said content clients as part of said pages.

3. The system of claim 2, wherein said at least one client-side time-out manager is defined as a server page for use along with a composition of pages rendered in said content client.

4. The system of claim 1, wherein said at least one client-side time-out manager is configured to detect activity for said session-dependent application and to ping said content server when activity is detected in said session-dependent application when said session-dependent application has been distributed to said content client.

5. A time-out management method comprising the steps of:

listening for activity in association with a session dependent application rendered in a client-side content browser; and

,

responsive to detecting said activity within a pre-specified client-side time-out interval, notifying a content server host of said session dependent application to maintain a session between said client-side content browser and said content server host.

6. The method of claim 5, further comprising the steps of:

determining a time-out condition in said client-side content browser;

rendering a prompt to continue said session; and

,

notifying said content server host to maintain said session if a response to said prompt is detected.

7. The method of claim 5, further comprising the step of establishing said time-out interval to be less than a time-out interval defined for said content server.

8. The method of claim 5, further comprising the step of performing said listening and notifying steps in a server page aggregated with other pages in a composition of pages in said client-side content browser.

9. The method of claim 5, wherein said notifying step comprises the step of, responsive to detecting one of mouse movement, a mouse click or a keyboard stroke in said client-side content browser within a pre-specified client-side time-out interval, notifying a content server host of said session dependent application to maintain a session between said client-side content browser and said content server host.

10. A machine readable storage having stored thereon a computer program for time-out management, the computer program comprising a routine set of instructions which when executed by a machine cause the machine to perform the steps of:

listening for activity in association with a session dependent application rendered in a client-side content browser; and

,

responsive to detecting said activity within a pre-specified client-side time-out interval, notifying a content server host of said session dependent application to maintain a session between said client-side content browser and said content server host.

11. The machine readable storage of claim 10, further comprising a routine set of instructions for causing the machine to perform the steps of:

determining a time-out condition in said client-side content browser;

rendering a prompt to continue said session; and

,

notifying said content server host to maintain said session if a response to said prompt is detected.

12. The machine readable storage of claim 10, further comprising a routine set of instructions for causing the machine to perform the step of establishing said time-out interval to be less than a time-out interval defined for said content server.

13. The machine readable storage of claim 10, further comprising a routine set of instructions for causing the machine to perform the step of performing said listening and notifying steps in a server page aggregated with other pages in a composition of pages in said client-side content browser.

14. The machine readable storage of claim 10, wherein said notifying step comprises the step of, responsive to detecting one of mouse movement, a mouse click or a keyboard stroke in said client-side content browser within a pre-specified client-side time-out interval, notifying a content server host of said session dependent application to maintain a session between said client-side content browser and said content server host.
