unfortunately no, The users be hitting both 11g and 10g servers as eventually all of the 10g servers will be switched out to 11g. They are planning on switching them out one by one. The Java JRE caches based on the entire URL, I was thinking that I could have an iRule that would change the response URL to that of the pool member. I think that would break because the client would be requesting the site from the VS and when they receive a response from the URL of the pool member it would drop the response because it does not recognize that it sent a request to that server.
