ProxyPass question

Post #1 of 4 (2612 views)

Hello,

I have a site which is completelly dynamic (everything mod_perl)
I want to use mod_proxy+mod_perl setup so that mod_proxy serves all
the images and proxies dynamic content to mod_perl server.
Furthermore, all images reside in /pics directory (i.e.
http://the.site.com/pics/logo.gif),
and I _really_ do not want to change this.

Here is a problem I ran into:
I have the following lines in httpd.conf file to proxy dynamic content to
mod_perl
ProxyPass / http://my_backend_server/
ProxyPassReverse / http://my_backend_server/

I cannot find a way to make mod_proxy server handle pics. I tried
Alias /pics/ "/some/dir/", AliasMatch, and god knows what else...nothing
worked

It seems that ProxyPass kicks in before any other uri transitions happen...

Any ideas or suggestions would be greatly appreciated.

Thanks.

Rewrite to the rescue!

RewriteLogLevel 1
RewriteLog "| /usr/local/apache_proxy/bin/rotatelogs /usr/local/apache-common/logs/r_log 86400"

<VirtualHost 0.0.0.0>

RewriteEngine on
RewriteOptions inherit
RewriteRule (^.+\.(mtpl|tmpl|mpl|cgi)$) http://your.backend.com$1 [P]

</VirtualHost>

What you want to do is something like this:

RewriteEngine On
# handle GIF and JPG images, traditional CGI's directly
RewriteRule \.(gif|jpg|png|css|txt|cgi)$ - [last]
RewriteRule ^/cgi-bin - [last]
# pass off everything but images to the heavy-weight server via proxy
RewriteRule ^/(.*)$ http://localhost:4077/$1 [proxy]

That is, first, handle locally what you want to handle locally, then
hand off everything else to the back-end guy.

Thank you VERY much.
I've been struggling with this problem for quite a while.
Yesterday I tried using mod_rewrite, but I guess I lack experience there.
I tried your suggestion -- works like a charm.

Thanks a lot.
