persistent session

I have a noob question. I have web servers that are hitting an f5 for round robin load balancing to a pool of applications servers. I need to configure the f5 so when a web server hits the f5, that it keeps going to the same application server the entire session.

    Hello.

    ​

    Your best option is to use cookie (session) persistence. You have some different flavours. I recommend you to check this out:

      Would this work between 2 servers with an f5 between them?. The whole chain is client --> f5 --> web server --> 2nd f5 --> application server.

      ​

      With how the application server programmers have it coded. The client has to hit the same web server and application server during the session.

        Definitely. In that you should have to apply persistence in both devices. Decrypting (SSL Bridging) could be mandatory depends on the scenario.
