== Reverse Proxy for a Subdomain ==

The below Apache reverse proxy configuration lets another website be served through a domain. The example is a little contrived.

{{{#!highlight apacheconf numbers=off
<VirtualHost 72.36.165.250:80>
  ServerName proxied-site.samat.org

  ProxyPass / http://google.com/
  ProxyPassReverse / http://google.com/
</VirtualHost>
}}}

== Cached Reverse Proxy ==

Use Apache's mod_disk to cache all requests made to a reverse proxy. For example, to setup a mirror to mirrors.kernel.org:

{{{#!highlight apacheconf numbers=off
# Configure mod_disk_cache (usually in /etc/apache/mods-enabled.d/disk_cache.conf)
<IfModule mod_disk_cache.c>
  CacheRoot /path/to/cache
</IfModule>

# Configure reverse proxy
<VirtualHost 72.36.165.250:80>
  ServerName proxied-site.samat.org

  CacheEnable disk /

  ProxyPass / http://mirrors.kernel.org/
  ProxyPassReverse / http://mirrors.kernel.org/
</VirtualHost>
}}}

== Apache logging ==

{{{#!highlight sh
# access.log should be vhost_combined by default
sed -i 's/other_vhosts_access/access/g' /etc/apache2/conf.d/other-vhosts-access-log

# Remove logging
sed -i '/^\s*ErrorLog/d' /etc/apache2/sites-available/default
sed -i '/^\s*CustomLog/d' /etc/apache2/sites-available/default
}}}
