I want to combine 3 iRules that are all redirects without "too many redirects" error

Hello,

You can use the switch command within a single irule :

switch -glob [string tolower [HTTP::path]] {
      "/uri/for/pool1/*" -
      "*pool_one*" -
      "/another/uri/*" {
         log local0. "Matched pool 1 paths for [HTTP::uri]"
         pool pool1
      }
      "/uri/for/pool2/*" {
         log local0. "Matched pool 2 paths for [HTTP::uri]"
         pool pool2
      }
      default {
         log local0. "Hit default for [HTTP::uri]"
         pool pool_default
      }
   }

And you can check if the irule is triggered within an https or http VS using the following condition :

if { [PROFILE::exists clientssl] == 0 }
