Why was it blocked?

Question

I write several lines of codes to get files from the webserver. First I set up a socket (port 80).
Socket connection;
connection=new Socket(hostname,80);
Writer o=new OutputStreamWriter(connection.getOutputStream());
o.write("GET /head.html HTTP/1.1 \r\n");o.write("Host:"+hostname+"\r\n\r\n");o.flush();
InputStreamReader in=new InputStreamReader(connection.getInputStream());
int c;
while((c==in.read())!=-1) {System.out.print(c);}
System.out.println("This is the end");
The problem is: the file "head.html" can be read and shown on screen but the program is blocked. I mean I cannot see the "This is the end" . After somewhile, the connection is timed out. Please tell me what is wrong. Many thanks.
P.S. the Webserver is using Apache 1.3.14.

Hi, this is basically your code from above, when I run it it works fine, the last line is executed and the program terminates normally. Try this and see if it works for you. I replaced head.html with index.html and successfully connected to www.yahoo.com and was returned the index.html file (and was printed to the console). Maybe try the same thing I did, then try it on your own server. If you then have a problem it might be a server problem?
java HttpGetTest www.yahoo.com
import java.net.*;
import java.io.*;
public class HttpGetTest {
    public static void main(String args[]) {
        Socket connection;
        try {
            String hostname = args[0];
            connection=new Socket(hostname,80);
            Writer o=new OutputStreamWriter(connection.getOutputStream());
            o.write("GET /index.html HTTP/1.1 \r\n");
            o.write("Host:"+hostname+"\r\n\r\n");
            o.flush();
            BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String line = null;
            while((line=br.readLine()) != null) {
                System.out.println(line);
        } catch (Exception e ) {
    System.out.println("This is the end");
}
