domain bypass ?

Hi,

That looks like a good start. You should add a hyphen after abc.com so that def.com is considered as part of the same condition. Also, if you're not using wildcards, you can remove the -glob flag. Finally, the host header isn't case sensitive, so you could set it to lower case before doing your comparison.

when HTTP_REQUEST {
   switch [string tolower [HTTP::host]] {
      abc.com -
      def.com {
         pool pool_a
      }
      default {
         pool pool_b
      }
   }
}
