session timeout

[kengwae]

Hi:

<session-config>
<session-timeout>20</session-timeout>
</session-config>

Does the above timeout starts from the time when the page is first loaded or starts from last key press/mouse move ? We need to calculate 20 minutes from last key press/mouse move.

Also how to alert the application 1 minute before the timeout ?

Please advise.

Best Regards,
yckok.

20 minute from the last http request made to the server from this session.

What do you mean by "alert the application"?
