Proxy Pass

Enable Proxy: [1]

sudo a2enmod proxy
sudo a2enmod proxy_http
systemctl restart apache2

Similar to forwarding, but takes care of redirects:

  ProxyPass         /mirror/foo/ http://foo.com/
  ProxyPassReverse  /mirror/foo/ http://foo.com/

Suppose the local server has address http://wibble.org/; then

  ProxyPass         /mirror/foo/ http://foo.com/
  ProxyPassReverse  /mirror/foo/ http://foo.com/

will not only cause a local request for the <http://wibble.org/mirror/foo/bar> to be internally converted into a proxy request to <http://foo.com/bar> (the functionality ProxyPass provides here). It also takes care of redirects the server foo.com sends: when http://foo.com/bar is redirected by him to http://foo.com/quux Apache adjusts this to http://wibble.org/mirror/foo/quux before forwarding the HTTP redirect response to the client.
