Hi Nick,

 

 

You can use string match to do the first part:

 

 

[string match {*DRC[0-9][0-9][0-9][0-9][0-9]*} [HTTP::uri]]

 

 

You could make the mastermenu and DRC checks more specific by using either HTTP::path or HTTP::query instead of HTTP::uri.

 

 

I tried the following, but couldn't quite figure out how to structure the first parameter of the string map to match on the host portion without using a regular expression.

 

 

Can you clarify this? Do you have multiple hosts that you're trying to rewrite in the redirect? Or do you want to rewrite all hosts to "def.example.com"? You can parse the host from the redirect location using URI::host:
