libnetworkcache - Client for ShaCache and ShaDir HTTP Server
Project description
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.
