f5 sharepoint tenacious session issue

I have this same issue and have a call open with F5 about it. They've now submitted an RFE for me so maybe if you request the same we might get some momentum?

For us the F5 is replacing ISA on a customer network and through the ISA all functionality works correctly and if you close the browser this kills the session correctly.

Deciding between leaving the session available for 15 minutes in an Internet cafe or not being able to edit documents in native applications just isn't an option. Neither is reducing the 15 minutes idle period since this will again frustrate users who may be compiling an document to upload in to the system.

I've considered an iRule to detect browser close to then delete the user session from F5 but then you have to identify whether a user has multiple tabs open etc so you don't bin them out until the last one closes..
