The only way I can think of handling this is to use a regular expression. I'm not sure whether it's better to use the regex or list out all possible values for the port.

If you wanted to list out all of the ports you could use a datagroup for simplified management.

Else, here's an example using regsub.

TCL man page for regsub: Click here


when HTTP_RESPONSE {
   set location [HTTP::header value Location]
    check to see if the Location header is set
   if { not ($location == "") {
       look to see if there is a string that contains a ":" followed by any number of digits followed by a forward slash
        if so, replace that string with a forward slash
      
      regsub {:\d+/} $location "/" newLocation
       replace the existing Location header with the new value
      HTTP::header replace Location $location
   }
}
