redirect to to 301 location

It didn't have to be numeric, script captured everything that followed "id=" so "id=abCD456" could be a match as well. I used numeric in my test because I assumed it was. 

Code for scripting a wildcard match is much simpler, but once again I'm concerned that all of your URLs have a fragment identifier, which (being a client-only feature) I believe is not being sent by browser -- therefore parser will not see that part with [HTTP::uri] or [HTTP::query]. 

when HTTP_REQUEST {
  if { [HTTP::uri] starts_with "/external/services/datastorage/" }{
    HTTP::respond 301 Location "https://different-website.domain[HTTP::uri]"
    }
}
