A simple HTTP Client The HTTPClient is composed of:

  • The actual client (HTTPClient)
  • Classes that act as a data repository, each of which deriving from the HTTPData class (HTTPText for short text content, HTTPFile for file I/O, HTTPMap for key/value pairs, and HTTPStream for streaming purposes)
