Detailed Description

HTTP_Client is intended to provide application API to classes that wish to do network i/o at a very high level of abstraction.

This class provides the ability to retrieve data from the network, of specified length and offset, and potentially use any protocol "under the hood" to do so. It currently uses HTTP. See HTTP_Handler also.
