iRule Assistance

Hello, Glorious people of DevCentral, I am facing an issue with a couple of iRules that are doing the same thing. First off, here is what the iRule looks like: when HTTP_REQUEST { ...

Also, for what its worth, the 

match_regex
is a fairly expensive way to achieve what you want above. This is a more efficient method:

when HTTP_REQUEST {
    if { [string tolower [HTTP::host]] eq "example.home.com" } {
        switch -glob [HTTP::path] {
            "/home"   -
            "/home/*" -
            "/home/services"   -
            "/home/services/*" -
            "/home/services/register"   -
            "/home/services/register/*" -
            "/index"   -
            "/index/*" -
            "/default" -
            "/default/*" {
                pool myPool
                ASM::enable MyPoolASM
            }
        }
    }
}

It's probably also worth mentioning that /home/services(/.*) and /home/services/register(/.*) are covered by the /home(.*) branch. Also, your regexps end with the literal ?, but that is not part of 

HTTP::path
, so that will never match.
