Preventing URLs from Being Reverse Proxied

ProxyPass /images/ ! ProxyPass / http://crm.example.com

It is possible to prevent certain URLs from not being proxied by specifying an exclamation mark (!) as the remote site URL in ProxyPass directives. It is important that those directives be placed before other ProxyPass directives. For example, this configuration will pass all requests to a backend site, except requests for images, which will be served locally.
