apt−proxy − A proxy for saving bandwidth to Debian servers
apt−proxy [options] [logfile]
is a python program designed to be run as an stand alone
server via twistd, and provides a clean, caching,
intelligent proxy for apt−get, which speaks
HTTP to apt−get clients, and http, ftp or rsync to the
backend server(s). apt-proxy listens by default on port

Configuration file. This defaults to /etc/apt−proxy/apt−proxy−v2.conf
Once apt−proxy is configured on a host SERVER, users then edit their sources.list file to point to the proxy (which uses the http protocol to serve clients), like so:
deb http://aptproxy:9999/security stable/updates main contrib non−free
What path should be specified after the server name and port number depends on the configuration of apt−proxy (which can restrict paths and send different paths to different servers). See SERVER CONFIGURATION below.
Note that you can also use the nicknames ’unstable’, ’frozen’ etc, but Packages/Sources files may get duplicated, so it is best to use either the symbolic or the code name and stick with it.
See apt−proxy.conf(5) for details of how to set up apt−proxy to use backends near to you.
apt−proxy reduces the bandwidth requirements of Debian mirrors by restricting the frequency of Packages, Releases and Sources file updates from the back end and only doing a single fetch for any file, how ever many users request it from the proxy.
/etc/apt−proxy/apt−proxy.conf or /etc/apt−proxy/apt−proxy−v2.conf
Packages are not compressed using gzip −−rsyncable, which gives a 30% reduction in bytes transferred for binary packages, and much greater for source and other packages.
apt−proxy v2 was written by Manuel Estrada Sainz and is maintained by Otavio Salvador and Chris Halls.
