Sending Information to a Remote Site 

• Just as it is easy to receive data from a server, it is also easy to send data to a server, or more likely, to a CGI script on a server. 
• In this case, we will use an output and print stream instead of an input stream as in the following example. 

try
  {
  Socket s = new Socket("www.extropia.com", 
                         80);
  OutputStream os = s.getOutputStream());
  PrintStream ps = new PrintStream(os);
  ps.println("POST /cgi-bin/test.cgi");
  ps.println("Content-type: plain/text");
  String string = "Hello CGI Script!";
  ps.println("Content-length: " + 
             string.length + "\n");
  ps.println(string);
  }
catch (IOException e)
  {
  System.out.println("Error: " + e);
  }

• Of course, you could simply use the GET method by passing the data as URL encoded information by replacing the first println line above with something more like: 


ps.println("GET /cgi-bin/test.cgi?phrase=Hello+CGI+Script");
