Hi Bill If you just want the problem to go away, then look for the attribute request.registerRequests in http://tomcat.apache.org/tomcat-5.5-doc/config/ajp.html .  If that is set to false, then there is no locking within the checkRequest method.  You lose that ability to get stats for the

Hi Chris, Wow, does that really work? That's a tremendously cool hack, if so! It seems to, although it's not yet been tested in anger and there is scope for dependancy issues if you navigate from one domain directly to the another expecting a continous session experience. What I mean is that
