Port Translation

You will need to find what is sending the 301 Redirect (sounds like the server(s)) and stop it there.

This should capture the redirect from the server and change the "server1" value to "test1". If the server is indeed sending this redirect back to the requestor, then this iRule will create and endless loop between the two.

when HTTP_RESPONSE {
if { [HTTP::is_redirect] } {
HTTP::header replace Location [ string map  {"server1" "test1"} [HTTP::header Location] ]
}
}
