In looking into this further, it appears that the difference isn't in HTTP vs AJP, the difference is in async vs synchronous.
The AJP traffic was carrying requests that were being processed asynchronously in Tomcat. If I switch to using the HTTP connector for this same traffic I still don't see anything in the access log. Other requests that are being processed synchronously are showing up in the access logs. I'm starting to step through the Tomcat code now, but any thoughts on this would be appreciated. - Chris On April 6, 2011 03:31:18 pm Chris Dumoulin wrote: > Thanks for your response Andre.
