Hi Nicole,

Yes, I was talking about mod_jk2.
I guess that it is possible to enable a worker by configuration.

Sorry, as I'm neither using apache 2 nor mod_jk*, I can't
add much. That was just third hand
AFAIK there is no way to disable this by configuration.
Just an idea:
Implement a servlet filter and a custom ResponseWrapper.
The ResonseWrapper can have it's own encodeURL that returns
the url unmodified.
Map that filter to every request.

I'm not shure about the response code that is returned

It's possible that tomcat returns a different response code
for a html and a jsp. (Like 200 for html because the html
error page was found and some other value for the jsp because
the jsp explicitly sets an response code.)
