Brendan,
I had a similar experience back in April and solved it by hacking
mod_webapp myself. I tried posting my problem to tomcat-dev only to be
greeted with credulity as Tomcat takes the high road with respect to being
a reference implementation and mod_rewrite lets you do things Sun's
specification specifically prohibits. None-the-less, I am true believer in
mod_rewrite and was un-willing to give it up, especially because there are
things you just can't do without it.
Below is a listing of my hack to mod_webapp.c. It works fine on RH Linux
6.2 and 7.2, but I have not tried it on Windows, so you're on your own as
far as compiling it.
Hope this helps,
Dan
