Hi John,

If you want to rewrite the HTTP host header value to the IP address of the selected server, you can use an iRule like this: 


when HTTP_REQUEST_SEND {

    Force evaluation in the clientside context
   clientside {

       Replace the Host header value with the selected server IP address
      HTTP::header replace Host [LB::server addr]
   }
}
