serve all requests via proxy *except* a specific one

I have the following in my httpd.conf

<VirtualHost *:80>
    ServerName foo.org
    ServerAlias www.foo.org

    <Proxy *>
        Options FollowSymLinks MultiViews
        Order allow,deny
        Allow from all
        AllowOverride All
    </Proxy>

    ProxyPass        / http://127.0.0.1:5012/
    ProxyPassReverse / http://127.0.0.1:5012/
</VirtualHost>

This works well as all requests for http://foo.org get served from port 5012 using a different web server. However, I want to serve just http://foo.org/lib via Apache from port 80. How do I do that? Adding the following lines to the conf doesn't help

Alias /lib /path/to/lib

<Directory "/path/to/lib">
    AllowOverride None
    Options None
    Order allow,deny
    Allow from all
</Directory>

Solution 1:

You can avoid proxying for a specific location by telling mod_proxy to ignore it with a ! for a destination:

ProxyPass        /lib !
ProxyPass        / http://127.0.0.1:5012/
ProxyPassReverse / http://127.0.0.1:5012/
