In a Microsoft Forefront Unified Access Gateway 2010 array deployment, Web Monitor may not display some security events in the Event Viewer window. This issue may occur after some user request receives an "Invalid HTTP request version" error message. This error is reported in Web Monitor as "Warning #18: Invalid Request Version."
This issue occurs because Web Monitor may incorrectly parse the XML query and not display some logged events after a "Warning #18: Invalid Request Version" HTTP event is reported. This issue occurs only in a Unified Access Gateway array deployment.
