-It works as wrapper of python httplib to use the Networkcache HTTP Server.
-
-API
----
-So, it must provide 2 methods:
-
- put(file)
- ''' Upload the file to Networkcache HTTP Server using PUT as HTTP method.'''
-
- get(key)
- ''' Download the file from Networkcache HTTP Server using GET as HTTP method.'''
