iRule not hitting default pool?

add the following to the irule to see what are we getting back from the server

when HTTP_RESPONSE {

log local0.debug "server Status respose [HTTP::status] if you get 301 or 302 is a redirect, 4XX are authentication and page not found, 200 good respose from the server"
log local0.debug "Http::header [HTTP::header names ] "
log local0.debug "header location [HTTP::header Location]"

}
