Abstract

A method for increasing server capacity may include causing a program to run in a browser in response to a session on a server. The program may be adapted to spawn a new browser window in response to a web page associated with the session being unloaded. The method may also include destroying all data associated with the session in response to a signal from the spawned browser window. The method may further include returning memory occupied by the data associated with the session to a memory pool.

Claims

1. A method for increasing server capacity, comprising:

causing a program to run in a browser in response to a session on a server, wherein the program is adapted to spawn a new browser window in response to a web page associated with the session being unloaded;

destroying all data associated with the session in response to a signal from the spawned browser window; and

returning memory occupied by the data associated with the session to a memory pool after destroying all data associated with the session.

2. The method of claim 1, further comprising setting the spawned browser window to a URL adapted to signal the server to destroy all data associated with the session.

3. The method of claim 1, further comprising transmitting the signal to the server to destroy all data associated with the session in response to the web page being unloaded.

4. The method of claim 3, further comprising causing the spawned browser window to automatically close itself after signaling the server.

5. The method of claim 1, further comprising causing the spawned browser window to not be viewable by a user.

6. The method of claim 1, further comprising causing the spawned browser window to be spawned off-screen and outside of a user'"'"'s control.

7. The method of claim 1, wherein causing the program to run in the browser comprises adding one of a JavaScript, ActiveX control, browser plug-in, modified browser runtime, JavaScript listener, and JavaScript event handler to every web page created by a web application during the session.

8. A system for increasing server capacity, comprising:

a data structure to cause a program to run in a browser in response to a session on a server, wherein the program is adapted to spawn a new browser window in response to a web page associated with the session being unloaded;

a data structure to cause all data associated with the session to be destroyed in response to a signal from the spawned browser window; and

a data structure to return memory occupied by the data associated with the session to a memory pool after destroying all data associated with the session.

9. The system of claim 8, further comprising a data structure to cause the spawned browser window to be set to a URL adapted to signal the server to destroy all data associated with the session.

10. The system of claim 8, further comprising a data structure to cause the signal to be transmitted to the server to destroy all data associated with the session in response to the web page being unloaded.

11. The system of claim 10, further comprising a data structure to cause the spawned browser window to automatically close itself after signaling the server.

12. The system of claim 8, further comprising a data structure to cause the new browser window to be spawned off-screen and outside of a user'"'"'s control.

13. The system of claim 8, further comprising a data structure to add one of a JavaScript, ActiveX control, browser plug-in, modified browser runtime, JavaScript listener, and JavaScript event handler to every web page created by a web application during the session to spawn the new browser window in response to a web page associated with the session being unloaded.

14. A computer program product for increasing server capacity, the computer program product comprising:

a computer readable medium having computer readable program code embodied therein, the computer readable medium comprising;

computer readable program code configured to cause a program to run in a browser in response to a session on a server, wherein the program is adapted to spawn a new browser window in response to a web page associated with the session being unloaded;

computer readable program code configured to cause all data associated with the session to be destroyed in response to a signal from the spawned browser window; and

computer readable program code configured to return memory occupied by the data associated with the session to a memory pool after the data associated with the session has been destroyed.

15. The computer program product of claim 14, further comprising computer readable program code configured to cause the spawned browser window to be set to a URL adapted to signal the server to destroy all data associated with the session.

16. The computer program product of claim 14, further comprising computer readable program code configured to cause the signal to be transmitted to the server to destroy all data associated with the session in response to the web page being unloaded.

17. The computer program product of claim 16, further comprising computer readable program code configured to cause the spawned browser window to automatically close itself after signaling the server.

18. The computer program product of claim 16, further comprising computer readable program code configured to automatically close itself after signaling the server.

19. The computer program product of claim 17, further comprising computer readable program code configured to add one of a JavaScript, ActiveX control, browser plug-in, modified browser runtime, JavaScript listener, and JavaScript event handler to every web page created by a web application during the session to spawn the new browser window in response to a web page associated with the session being unloaded.
