Tomcat, pathinfo, and servlets

So today I learned that you can't just access PATH_INFO (pathinfo) information from a servlet when you're using Tomcat (at least not Tomcat 3.2.4 running under Apache). I can access the PATH_INFO information okay under Tomcat running standalone on my PC, but for some reason the same config did not work properly using Tomcat under Apache. (I'll investigate this more in the future.)

When I just had /Content as the url-pattern like I normally would, I kept getting a 404 error any time I pre-pended anything to the end of my servlet call (for instance, when I tried to hit a URL like But once I changed the servlet mapping as shown above, it started working like a champ.
