http://issues.apache.org/bugzilla/show_bug.cgi?id=38889 ------- Additional Comments From [EMAIL PROTECTED] 2006-03-08 16:47 ------- I see what mod_jk is doing in attempting to match the longest uri pattern first. The Servlet specification 2.4 (section SRV.11.1) says The container will recursively try tomatch the longest path-prefix. This is done by stepping down the path tree a directory at a time, using the / character as a path separator. The longest match determines the servlet selected. This definitely favors a longest match. However, I think it also implies that 'longest' means 'most uri path elements'. I'd like to submit a patch that brings mod_jk closer to this behavior. I'll attach the patch to this issue. Below are some JkLogFile examples to demonstrate what the patch does. * * * For what follows, I've set up an apache configuration with this list of workers defined: JkMount /*.jsp worker_default JkMount /a/* worker_a JkMount /a/1/* worker_a1 JkMount /a/1/2/* worker_a12 JkMount /golly-gee-batman/* worker_golly This is the order in which the JkMount directives appear in the httpd configuration -- the goal is to verify that `most path elements' gets preference. The first two samples of log output show a stock mod_jk 1.2.15; subsequent examples show a patched mod_jk 1.2.15. * * * # (unpatched mod_jk-1.2.15) # # Here, we submit a non-matching URI, just to see the iteration # order that mod_jk will use when attempting to locate a worker for # the request.
