>Description:
I have a pretty normal setup, with the following RewriteRule entries in httpd.conf:

RewriteEngine on
RewriteRule ^/img/(.*) http://www.sierra.com/img/$1

(Basically, anything in the top level 'img' directory should be pulled from our
live server).

However, when I request <http://eddie.sierra.com//img> I get a directory listing
of the top level img directory on eddie instead of getting forwarded to the top
level img directory on www.sierra.com.

So it seems that the Rewrite stuff is being called before the server cleans up
the URL -- such as replacing // with /.

Not that big of a deal, since people shouldn't put // in their URLs anyway, but
it happened at least once.
>How-To-Repeat:
http://eddie.sierra.com//img is an example how it goes wrong.

http://eddie.sierra.com/img gets redirected to http://www.sierra.com/img
>Fix:
Re-arrange the order of how the modules get called... clean up the URL first
and then pass it on to the modules. 

Honestly I haven't looked at the src much so I'm not sure if this is possible...

Let me know if I can help out in any way
