Introduction
The goal of libnetworkcache python library is to abstract the HTTP calls. It works as wrapper of python httplib to use the Networkcache HTTP Server.
- The Networkcache HTTP Server are sub-divided into two Web services:
SHACACHE
SHADIR
SHACACHE
It is a simple HTTP Server used to cache files.
SHADIR
It is a simple HTTP Server used to cache information, working like a directory.
