Introduction
apt-proxy is a program that caches the packages you download from the Internet, to your hard disk. Because apt-proxy behaves as if it were a HTTP server with a full copy of the repositories you select, you can access the packages from other computers on your network. If a package is not in the cache, apt-proxy automatically downloads and caches it. This can significantly decrease download bandwidth and installation time when you have to install the same packages repeatedly (i.e. an upgrade of multiple machines).
