I am running Apache 2.2 with Tomcat 6 and have several layers of URL rewriting going on in both Apache with RewriteRule and in Tomcat. I want to pass through the original REQUEST_URI that Apache sees so that I can log it properly for "page not found" errors etc.

In httpd.conf I have a line:

SetEnv ORIG_URL %{REQUEST_URI}

and in the mod_jk.conf, I have:

JkEnvVar ORIG_URL

Which i thought should make the value available via request.getAttribute("ORIG_URL") in Servlets.

However, all that I see is "%{REQUEST_URI}", so I assume that SetEnv doesn't interpret the %{...} syntax. What is the right way to get the URL the user requested in Tomcat?
