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;
