Mirroring the GNU Web Server

<VirtualHost>:

ServerName gnumirror.example.org
CacheRoot "/var/cache/mod_proxy"
CacheDefaultExpire 86400 # for Apache 2.0+, value is in seconds
ProxyPass / http://www.gnu.org/
CacheEnable disk /

Mirroring the GNU FTP server requires approximately 40GB disk space (as of 04 January 2007), which is distributed by the following way:

/gnu:                12G 
/non-gnu:           300M 
/old-gnu:           700M 
/gnu+linux-distros:  27G
