Use Socket to load a web page

   <source lang="java">

<%@ page contentType="text/html" import="java.io.*, java.net.*" %> <% 

       try {
           Socket s = new Socket("www.jexp.ru", 80);
           BufferedReader in = new BufferedReader(new 
               InputStreamReader(s.getInputStream()));
           PrintWriter socketOut = new PrintWriter(s.getOutputStream());
           socketOut.print("GET /index.html\n\n");
           socketOut.flush();
           String line;
           while ((line = in.readLine()) != null){
               out.println(line);
           }
       } catch (Exception e){}
