Issues to forward requests with 'start with' due to similar contexts under same domain

Hi everybody, A network request that seemed to be simple is giving some trouble to our network team, I'd appreciate some help. Here's a summary of the rules to be put in place: 1) example.domain.c...

    Hi awakenings ,

    you might use the regexp, but using globbing is probably less CPU intensive:

    when HTTP_REQUEST {
   # Check the requested path (set to lowercase)
   # -glob: allow string pattern matching
   switch -glob -- [string tolower [HTTP::path]] {
      "/cali" -
      "/cali/" -
      "/cali/*" {
         log local0. "Matched pool 1 paths for [HTTP::uri]"
         pool pool1
      }
      "/california" -
      "/california/" -
      "/california/*"  {
         log local0. "Matched pool 2 paths for [HTTP::uri]"
         pool pool2
      }
      default {
         log local0. "Hit default for [HTTP::uri]"
         pool pool_default
      }
   }
}

    This will send traffic to /cali and following segments to pool1 while traffic to /california and following segments will be forwarded to pool2.

UPDATE: I just realized I can add just /cali and that should be it

when HTTP_REQUEST {

   # Check the requested path (set to lowercase)
   # -glob: allow string pattern matching
   switch -glob -- [string tolower [HTTP::path]] {
      "/cali" -
      "/cali/*" {
         log local0. "Matched pool 1 paths for [HTTP::uri]"
         pool pool1
      }
      default {
         log local0. "Hit default for [HTTP::uri]"
         pool pool_default
      }
   }
}


Thanks a lot! 🙂
