/ARCHIACjkaejksfsdjkhdfsj matches your first starts_with condition. Can you give a couple more examples of good matches versus bad matches? I'm not sure I have a clear enough picture of what is "good" to provide you a proper solution. On top of that, a few comments:

 

  • I'm not sure how anything gets through to the server with your HTTP::host. If you string tolower that, it'll never match xyz.APAC.com. I'm guessing that's just a sanitization error for adding to DC?
  • You don't need a string tolower on the HTTP::host. That is case insensitive by RFC.
  • You almost certainly do not want matches_regex there. Recommendation would be to use if, elseif, else strategy here, so by virtue of not matching your first two cases, the else will handle your 404 for everything else.
