caching proxy server for software repositories
Apt-Cacher NG is a caching proxy for downloading packages from Debian-style software repositories (or possibly from other types). . The main principle is that a central machine hosts the proxy for a local network, and clients configure their APT setup to download through it. Apt-Cacher NG keeps a copy of all useful data that passes through it, and when a similar request is made, the cached copy of the data is delivered without being re-downloaded. . Apt-Cacher NG has been designed from scratch as a replacement for apt-cacher, but with a focus on maximizing throughput with low system resource requirements. It can also be used as replacement for apt-proxy and approx with no need to modify clients' sources.list files.
