APM irule

We worked with F5 Support and support provided us with the following solution to disable APM policy for Exchange Web Services (EWS).

 priority 1
when HTTP_REQUEST {
    set is_disabled 0
    if { [string tolower [HTTP::path]] starts_with "/ews" } {
        if { [string tolower [HTTP::uri]] contains "wssecurity" } {
            NTLM::disable
            set is_disabled 1
            set path [HTTP::path]
            WEBSSO::disable
            ACCESS::disable
            HTTP::path _disable-$path
            pool Exchange_External_oa_pool7 
        }
        if { [string tolower [HTTP::uri]] contains "mrsproxy.svc"} {
            set is_disabled 1
            set path [HTTP::path]
            NTLM::disable
            WEBSSO::disable
            ACCESS::disable
            HTTP::path _disable-$path
            pool Exchange_External_oa_pool7 
            COMPRESS::disable
            CACHE::disable
        }
    }
    if { [string tolower [HTTP::path]] starts_with "/autodiscover" } {
        if { [string tolower [HTTP::uri]] contains "wssecurity" } {
            NTLM::disable
            set is_disabled 1
            set path [HTTP::path]
            WEBSSO::disable
            ACCESS::disable
            HTTP::path _disable-$path
            pool Exchange_External_ad_pool7 
        }
        if { [string tolower [HTTP::uri]] contains "autodiscover.svc"} {
            set is_disabled 1
            set path [HTTP::path]
            NTLM::disable
            WEBSSO::disable
            ACCESS::disable
            HTTP::path _disable-$path
            pool Exchange_External_ad_pool7 
            COMPRESS::disable
            CACHE::disable
        }
    }
}
when HTTP_REQUEST_RELEASE {
    if { !$is_disabled } { return }
        HTTP::path $path
        unset is_disabled
}
