apt-cacher-ng - 3.7.4-1.1 main

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.
