Basic HTTP redirect question on LB pool

Well, there is nothing that would otherwise prevent that from working. However, I'm not entirely sure that it accomplishes what you want. I think you may be better off using a Cookie to save the context across requests. For example:

when CLIENT_ACCEPTED {
   set add_cookie ""
}
when HTTP_REQUEST {
   if { [HTTP::cookie exists "MyCookie"] } {
       MyCookie contains the original pool used
      pool bea_pool
   } else {
       This must be the first access
      if { [HTTP::uri] contains "acces" } {
         pool bea_pool
         set add_cookie bea_pool
      } elseif { [HTTP::uri] contains "aide" } {
         HTTP::redirect "http://10.172.155.201/[HTTP::uri]"
      } else {
          What should happen here?
          Is there a default pool on the VS that
          will be used if none is specified here?
      }
   }
}
when HTTP_RESPONSE {
   if { $add_cookie ne "" } {
      HTTP::cookie insert name "MyCookie" value $add_cookie
      set add_cookie ""
   }
}
