Hi there I've been searching all over the internet about this problem. We have a web application running in Tomcat (5.0.28) and Apache (2.0.55) that is dropping parameters for some requests. The weird thing is.... the same request might drop the request parameters in some cases but not in others. We have enabled valves and filters in tomcat and it looks like the parameters are being drop somewhere between apache and tomcat. We know the URL and the request are well formed since the same request works most of the time. We are not doing redirection or any other thing that process the request before it gets to Tomcat. The few references I have found around the internet do not mention any solution whatsoever. Anybody has seen anything similar? any suggestions as for what I should try? Leo.
