host header load-balancing

Thank you for your reply. There seems to be a loop in the iRule. It now looks like traffic is being redirected to the virtual server again, with the suffix /login added, which obviously causes this loop when the user uses MSIE. I just would need the /login suffix added, and the pool site-10.130.14.98_9610 to be used. This is my current iRule :

when HTTP_REQUEST {
  switch -glob [HTTP::header value "User-Agent"] {
    "*MSIE 6*" -
    "*MSIE 7*" -
    "*MSIE 8*" {
    log local0. "[IP::client_addr]:[TCP::client_port]: Matched MSIE."
    pool site-10.130.14.98_9610
    HTTP::uri "/login"   
    }
    default {
    log local0. "[IP::client_addr]:[TCP::client_port]: Matched default pool" 
      pool site-10.130.14.98_29710
    }
  }
}
