SSL persistent& resumption - why doesnt work

The problem with SSL persistence is that it will either time out or eventually get renegotiated by either the client or the server. Browser are especially prone to SSL renegotiation, so SSL persistence is generally not a good persistence mechanism for web traffic. If you need to keep persistence over some very long period of time, and this is all exclusively browser-based traffic, I'd highly recommend persistent HTTP cookies. Create a cookie persistence profile and modify the expiration values, then apply that persistence profile to the virtual server.
