I see the same results in tomcat 4.0.2 and in jetty 3.1.3-1. DO I MISS SOMETHING???
Help!!! Is it ALWAYS that 2 requests for the SAME URI block???????????? I seem to raise the white flag fellas. If anybody can shed some light please do. In specs, discussions i have never seen any notion of the "URL" as far as concurrent servlet serving threads are concerned. Please HELP! I am really stuck, and all i wanna know is if this is the supposed behaviour or not. Thanx for any one volunteering to share his/her knowledge.
