today i have a problem with session handling:
I use session to login into admin area to view a project listing. So if i am a too long time on this listing page and try to edit per "edit-button", suddenly i got a failure window if i want to save edited data row.
If i login again, its working again, for some minutes.
Can someone please give me a hint how to handle this problem? Session Cookies and lifetime are set to 2 hours.
