Mongrel users - Aug 2006 - Apache 2.2 + Mod Proxy Balancer + Mongrel - Hot Linking Protection?

Hey guys,

Ok, basically I coded a ruby on rails CMS to manage a bunch of media  
files. I am finding that a lot of people are "hot linking" to these  
media files and would like to prevent this to save bandwidth. Usually  
in the past, it hasn''t been a problem, I would add something like the  
following to my .htaccess file

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www.)?domain.com.*$ [NC]
RewriteRule .(gif|jpg)$ - [F]

However, with my httpd config containing the following lines now:

ProxyPass / balancer://mycluster/
ProxyPassReverse / balancer://mycluster/
ProxyBlock images media
Options Indexes FollowSymLinks

The hotlink protection doesn''t really work anymore. Does anybody know  
how I could implement this?

Thanks,
Carl

Where in your config are the Proxy*-Directives, in a
Location/Director-Tag or in Global?

I think this is a question for the httpd-users list, imho.

I''m pretty sure that''ll still work, but you''ll want
to turn on the mod_rewrite debugging to see what happens.

I had a similar problem when I re-configured my server to use Apache +
mod_proxy + mongrel.  I had some rewrite rules to handle feeds
(re-directed to Feedburner), page caching (inspired by Coda''s howto)
and links from my previous blog engine. I couldn''t get re-write to
work until I dropped the ProxyPass lines and put the following in:

RewriteRule ^/(.*)$ http://localhost:3000%{REQUEST_URI} [P,QSA,L]

Now the all the other rewrite rules work as intended, and mongrel
still handles dynamic queries.
