Controlling access to your proxy

You can control who can access your proxy via the <Proxy> control block as in the following example:

<Proxy "*">
  Require ip 192.168.0
</Proxy>

For more information on access control directives, see mod_authz_host.

Strictly limiting access is essential if you are using a forward proxy (using the ProxyRequests directive). Otherwise, your server can be used by any client to access arbitrary hosts while hiding his or her true identity. This is dangerous both for your network and for the Internet at large. When using a reverse proxy (using the ProxyPass directive with ProxyRequests Off), access control is less critical because clients can only contact the hosts that you have specifically configured.

See Also the Proxy-Chain-Auth environment variable.
