iRule to disable APM not working as expected

Cannot save or edit the post so: APM is still causing grief for Mac clients. I am trying to disable the policy for Mac User-Agent headers. This is killing the session but resulting in a apm loop (it just creates an immediate subsequent session ID). Any ideas?

If your request has any of the apm cookies, you may need to remove them from that request. I've had weird issues like that.

so, perhaps your iRule could do something like this:

when HTTP_REQUEST {    
    if {[string tolower [HTTP::header "User-Agent"]] contains "mac os x"  && [string tolower [HTTP::uri]] equals "/ews/exchange.asmx"} {
        log local0. "  Disable access for [HTTP::uri]"
        ACCESS::disable 
        HTTP::cookie remove "MRHSession"
        HTTP::cookie remove "LastMRH_Session"
    } else {
        log local0. "  [HTTP::uri]"
    }
}

May want to try with

when CLIENT_ACCEPTED {
    ACCESS::restrict_irule_events disable
}
