Subject A optimizing problem, need your help.
Date Thu, 23 May 2002 01:40:03 GMT
Following call stack is dumped from Tomcat server. You can see it is so
deep. What's all these StandardPipeline.invokeNext() calls about? How
can I short circuit the pipelines since I don't use them? Similarly, can
I turn off ApplicationFilterChain because I don't plan to use servlet
filter as defined in Servlet 2.3 API.
