sticky sessions and proxy
We have a specific problem and hope someone has an idea what could be the cause.
We use persistence profiles (cookie and source ip for sticky sessions) for our web servers. We have placed a reverse proxy for A/B testing between the web servers and F5. Unfortunately the sticky session doesn't work anymore.
the setup:
Internet -> F5 Virtual Server (contains a irule to redirect sub-domains to the f5 proxy pool and configured persistence profile with cookie01 and snat) -> f5 proxy pool -> proxy -> F5 Virtual Server that contains the web server pool (persistence profile with cookie02 and snat) -> web server
On the web server logs, proxy log and in the browser we see the cookies, but if we do some upload test from the same source, we always land on different web server.
