  • The key here is whether the session timer is tied to any tcp idle timeouts. I'd think no, and if that is the case that's better, as a 20 minute timer at tcp level would open you to port exhaustion in even a mild DDoS event. Have you taken a tcpdump to see if the client is doing a new handshake after those 10 minutes or if it's just acking on an existing tcp session? – Jason Rahm Jan 06 '16 at 17:57

If the MachineKeys in the config on both servers are identical, upping the timeout to 20 minutes should work. If that doesn't work, or you don't have the rights to do so, you'll need a keep-alive in your asp.net application like in this question
