     during extended testing we found out that there is an issue with the irule, it looks like some of the subsequent http POST requests not getting the URI appended.

    packet capture (from F5 to backend XML) shows successful attempts have full URI added to the http request but unsuccessful attempt doesn't have URI path added. Any suggestions?

      why subsequent http post does not send appended URI ? F5 sent append URI on initiation http request ?
