Generate forward proxy as virtual host

The new class and acompanying template allow the simple configuration of a forward proxy in a virtual host. Very handy for using a separate port with the vhost for the proxy.

Provoding a network to which the proxy is restricted is required. 

Still you could use 0.0.0.0/0 if you want to ;-(

Usage:

apache::vhost::forward_proxy { 'vproxy':
   port => '9090',
   allowednet => '192.168.0.0/24',
 }
