URL redirection with retaining the original on browsers

Are trying to convert the links inside the HTTP response from www.abc.test.com to www.test.com again?

You can create a new stream profile to translate the domain names or use an iRule like this:

when HTTP_REQUEST {
   set to_change 0
      if { [HTTP::path] contains "/urltomonitor" } {
         set to_change 1
   }
   STREAM::disable
}

when HTTP_RESPONSE {
   if { $to_change == 1} {
      set original "http://www.abc.test.com"
      set replacement "http://www.test.com"
      STREAM::expression "@$original@$replacement@"
      STREAM::enable
   }
}

You will need to modify the [HTTP::path] to match your url that contains redirection, and you still need to attach "stream" profile to your virtual server.
