Detailed Description

A TCP/IP socket for the HyperText Transfer Protocol version 1.0.

When acting as a client, the procedure is to make the connection to a remote server, then to retrieve a document using the following procedure:

      PHTTPSocket web("webserver");
      if (web.IsOpen()) {
        PINDEX len;
        if (web.GetDocument("http://www.someone.com/somewhere/url", len)) {
          PString html = web.ReadString(len);
          if (!html.IsEmpty())
            ProcessHTML(html);
        }
        else
           PError << "Could not get page." << endl;
      }
      else
         PError << "HTTP conection failed." << endl;
