Seems like there's plenty of over-complication in your current rule. You don't need to overwrite server responses as only the URI was modified. It does not violate cross-domain policy and user browser has no problem with it. Furthermore, it has no awareness the response content did not originate from the originally requested directory.

The iRule below should cover your needs:

when HTTP_REQUEST {

    if {[HTTP::uri] contains "/study1"} {
      HTTP::header remove "Accept-Encoding"
      HTTP::uri "/ServiceStudyDB"
      STREAM::disable
    }
}

Thank you for the response and I have tested the simplified iRule. The problem exists when the server has a 302 from within itself to send the requesting URL to /ServicesStudyDB/login.aspx.... Therefore, are "response" rewrite is also required as the requesting browser should only know about /study1. Keep in mind the reason for this is that as we add /study2, /study3, etc.. we will be sending to specific backend nodes and need to keep the URI string on the request in order to send to the correct backend server. Seems the response is the loop. I have this working on the Cisco ACE with some major manipulation and being tasked with getting this to workon on the F5 (which seems possible).
