Combine iRules

Hi Jeff,

A switch statement (Click here) would help you organize the two rules into one:

when HTTP_REQUEST {
   log local0. "Client [IP::client_addr] requested [HTTP::host][HTTP::uri]"
   switch -glob [HTTP::uri] {
      */ABC* -
      */DEF* {
         log local0. "Client [IP::client_addr] matched first case, sending to pool WLS-V10."
         pool WLS-V10
      }
      */XX3333* {
         log local0. "Client [IP::client_addr] matched second case, rewriting URI to /ABC/, sending to pool WLS-V10."
         HTTP::uri [string map {/XX3333/ /ABC/} [HTTP::uri]]
         pool WLC-V10
      }
      */XX4279* {
         log local0. "Client [IP::client_addr] matched third case, rewriting URI to /ABC/, sending to pool WLS-V10."
         HTTP::uri [string map {/XX4279/ /ABC/} [HTTP::uri]]
         pool WLC-V10
      }
      default {
         log local0. "Client [IP::client_addr] didn't match any case."
      }
   }
}

This should exactly replicate your two rules. Note that the -glob flag on switch enables wildcard matching. So the *'s will match any number of any characters. If you only want to match requests with URIs starting with /ABC or /DEF, use /ABC* and /DEF*.

If you're not sure that the rule is working correctly, uncomment the log statements and check the /var/log/ltm log file (tail -f /var/log/ltm).
