Apt-Cacher NG is a caching HTTP download proxy for software packages, primarily for Debian/Ubuntu clients.

Apt-Cacher-NG is partially based on concepts of Apt-Cacher but is rewritten with a main focus on performance and low resource usage.

The package reuses many ideas behind the other famous proxy, its predecessor apt-cacher 1.x (which has been written in Perl). In contrast to apt-cacher, other aspects have been declared as primary targets during the development of apt-cacher-ng:

- lightweight implementation - allow the use on systems with low memory and processing resources
- internal (native) threading - avoiding process fork'ing wherever possible, avoiding kludges for pseudo-thread synchronization, avoiding excessive use of hidden file system features for internal operations
- real (effective) support of HTTP pipelining, therefore a native client with native stream control has been developed. The nice side effect is the reduction of resource overhead and minimization of possible points of failure
- avoiding featurities where they cause too much bloat and the functionality can be provided by native OS features
- reliable but efficient content merging in the local package pool, avoiding delivering of wrong data.

Build instructions:

- run "make". Output goes to the "build" directory. apt-cacher-ng is the regular version, apt-cacher-ng-debug is for debugging purposes only.

For compiler flags, see CMakeLists.txt file.
