Redirect on user browser inactivity on LTM VIP

We have a type Standard F5 LTM VIP (no APM, no ASM,  just LTM) with a pool of application servers.  

Only SSL, TCP and HTTP profiles are applied to that VIP. Connection is made by browser to URL https://www.mysite.com/mypage and web page content displayed. All good at this point.

Then a user is idle for 20 minutes doing nothing.

We want in this case of inactivity to send http redirect from F5 to a user browser to redirect to https://www.mysite.com

Again this is a very basic VIP; beside TCP profile idle timeout I don't see any other posisble timeouts and TCP idle timeout is totally different from what we want to do...

Any suggestion how our goal can be achieved?

Thanlk yuo in advance!

  • Correct, other than keep-alive no data. Request came from applicaiton team; for them idle conneciton is no browser activity. They don't care or don't know about lower OSI model levels activity, like TCP keep-alive.

      Dmitriy_Tiper Sadly, the only thing that I have seen recently is someone creating a counter that will arbitrarily close a connection after x amount of time used rather than closing a connection that has no data traversing it over a certain period of time. The best option here would be to disable TCP keepalive on the server side if open connections is the large of a problem.

  • Dmitriy_Tiper Is the issue here that the client connections are remaining active without any data traversing them other than the tcp keepalive?
