I installed WireShark on the application server's. I observer below situation:
request1 (logging) -> AppServer1 (OK) request2 (search product) -> AppServer1 (OK) request3 (product details) -> AppServer1 (OK)
--------- Delay (more than 180sec)
request4 -> AppServer2 and logout.....
Why request is redirect on AppServer2??

You're right, http is stateless and tcp is stateful.
You said the issues occur since you've changed from a Microsoft product to a F5, so I would search here for the differences. It's not new to me that Microsoft has it's own interpretation of RFCs.
If the problem is reproducible, I would recommend a Wireshark trace on the app server and client and compare them. Maybe you need to do further investigation on the "middle-ware" (like the F5 or Firewall) if the traces don't corelate.

HTTP is stateless protocol in application layer. Is problem in idle Time TCP? I'm not sure.
Automatic logout occurs in different time interval < session timeout ASP app.
How I can verify this problem on the app server? Maybe Wireshark?

Hi dexter,
I guess the default Idle timeout on your F5 is 300 seconds for TCP connections. If you want to set a higher value for this, have a look in your tcp profile.
Hope this helps, Manuel
