Subject: servlets forbidden when using rewrite module?
Date: Mon, May 10, 1999, 8:10 PM

I've gotten JServ 1.0b4 working just fine on my linux
redhat 5.2 installation.  I then compiled in the
mod_rewrite package, which also worked.  

My problem is, as soon as I turn the rewrite engine on
(RewriteEngine on) servlets immmediately stop working,
saying that acces to servlet is forbidden.

The servlet engine definitely seems to be running,
since when I access a jsp, it says "access to
/servlets/org.gjt.jsp.JSPServlet is forbidden" 

This is with no RewriteRules, or anything.  simply the
rewrite engine being on.

When I turn it off, servlets work again.

Hiya --

So it is indeed the case that stat was leaving r->finfo in an invalid
state; when I described this & suggested a patch, one of the people in the
Apache Group decided it wasn't a good idea to trust the value in r->finfo
after a failed stat call, and applied the following (related) patch:

This will be in the next version of Apache; please apply it rather than
the previously posted patch, and if you encounter any problems, drop me a
note.

thanks for the bug report!

I encountered this too and after scouring the rewrite_mod documentation, found a workaround!

RewriteEngine On
# whoops! with RewriteEngine On, JServ doesn't find about about servlets
# until we poke a hole like so (repeat for all zones):
RewriteRule ^/servlets/.* - [passthrough]
# redirect root to some servlet (requires mod_proxy)
RewriteRule ^/$ /servlets/SomeServlet [proxy]
