Problems with redirections

Update. What is happening at the moment (after playing with response profiles) is the first request goes to correct pool and is loaded, but there are stuff like "/Service_name/styles/default/style.jsp?" fail to load (as there is no client name and I have disabled the default pool), resulting only text to be loaded with no layout, pictures, etc. Seeing this I was thinking to configure pool persistence. Once the correct pool is chosen by the iRule, LTM should continue forwarding requests to the same pool. Can't find anything useful, so any suggestions about how to do it will be much appreciated.
