#215: regex matches sporadically on identical request

 Here's my VCL file:

 backend production {
   set backend.host = "192.168.4.81";
   set backend.port = "http";
 }

 backend old_production {
   set backend.host = "192.168.4.111";
   set backend.port = "8000";
 }

 sub vcl_recv {
   if (req.url ~ "/old.*") {
     set req.backend = old_production;
   }
   else {
     set req.backend = production;
   }

   if (req.request == "GET" && req.url ~
 "\.(gif|jpg|png|swf|css|js)(\?.*)?$") {
     lookup;
   }
 }

 On this URL (and URLs like it):

      http://gtd.1kstudios.lan/old/task_assignments/actualize/7482

 , the backend chosen occasionally is production, not old_production. This
 gets worse over time (i.e. over the course of weeks). Repeatedly reloading
 the same page will eventually result in it loading in the correct backend,
 only to fail again later on subsequent reloads.

 This is on Fedora Core 4 64-bit x86.
