For the mapping below, I hope you tried "/foo.txt" not "/foo.ext" :-)

No. Tomcat looks for <servlet-mapping>s that match the URL you specify first -- the
rules are right out of the servlet spec. It tries the matching in the following
order:
* Exact match against a mapping pattern
* Prefix match against a pattern like "/foo/*".
* Extension match against a pattern like "*.txt".
* Go to the default servlet (which, in Tomcat's case, serves
the content as a file.
Your goal is to be matched at the third stage -- by the extension. A couple of
details to keep in mind:
* URL matching is case sensitive, so a pattern "*.txt" will *not* match a path
"/foo.TXT".
* The extension must be on the very last element of the path (after the last slash).
My suggestion is that you first work on this with Tomcat stand-alone. After you see
how that works, then work on the Apache config.
