Parsing URI to Make Pool Selection

We finally were able to schedule time to test this, however all did not go according to plan.

I modified the iRule as follows

 
when HTTP_REQUEST {
    if { [string tolower [HTTP::path]] contains "/ws/test.asmx" } {
        if { ([matchclass [IP::client_addr] equals poolA.AllowList])} {
            pool poolA
            log local0. "Permitted: [IP::client_addr] --> [HTTP::host][HTTP::uri]"
        }
        if { ([matchclass [IP::client_addr] equals poolB.AllowList])} {
            pool poolB
            log local0. "Permitted: [IP::client_addr] --> [HTTP::host][HTTP::uri]"
        }
        else {
            discard
            log local0. "Denied: [IP::client_addr] --> [HTTP::host][HTTP::uri]"
        }
    }
}

It appears that

if { [string tolower [HTTP::path]] contains "/ws/test.asmx" } 

is not being evaluated properly. I took all entries out of both 'Data Group List' and I still am able to get to the page. In addition, I checked /var/log/ltm and there are no entries for this iRule.

Are changes to iRules applied immediately or do they need to be reloaded into memory?

Any suggestions?
