Now, I'm going to explain a program which will send a gentle HTTP request to the web server and displays the response headers and response body. This program will shows how a web browser fetches the information.

class WebClient
static public void main(String[] args)throws Exception
//create a Socket
//String a=args[0];
byte ipaddr[]={(byte)208,(byte)198,(byte)128,(byte)208};
Socket s = new Socket(InetAddress.getByAddress(ipaddr),80);
//Socket s=new Socket(InetAddress.getLocalHost(),8990);
System.out.println("Connected to Server Successfully");
PrintStream ps =new PrintStream(s.getOutputStream());
InputStream is = s.getInputStream();
//ps.println("GET / HTTP/1.1 \r\nHOST:inetsolv\r\n\r");
//ps.println("GET /test1/login.jsp");
ps.println("GET /cmint/home.html HTTP/1.1\r\nHOST:inetsolv\r\n\r\n");
byte b[] = new byte [10000];
// this is definitely a bad way of getting a web document
BufferedReader reader=new BufferedReader(new InputStreamReader(is));
String str="";
}catch(Exception e){ System.out.println(e);}

There are several ways to find the server and open the socket through as you can see comments from the above program.
