Trouble sending HTTP response with Java Socket

Question

I\'ve been trying to write the beginnings of a simple web server, but can\'t seem to get the response to get sent. I\'ve tried every type of Output stream imaginable but no

I've been struggling like crazy with a very similar issue.

After literally head-banding on the wall I found my issue was so trivial I kept on head-banging on the wall for a while.

Basically in my input while loop I was checking for a null line, but I forgot to check for an empty line (and subsequently break).

No guarantee it'll work the same for you but here's my one cent:

in = session.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String line = null;
while ((line = br.readLine()) != null) {
    System.out.println(line);
    // this seems to be the key for me! 
    // somehow I never get out of this loop if I don't 
    // check for an empty line...
    if (line.isEmpty()) {
        break;
    }
}
out = new BufferedWriter(
    new OutputStreamWriter(
        new BufferedOutputStream(session.getOutputStream()), "UTF-8")
);
out.write(OUTPUT_HEADERS + OUTPUT.length() + OUTPUT_END_OF_HEADERS + OUTPUT);
out.flush();
out.close();
session.close();

My constants are:

private static final String OUTPUT = "
Worked!!!
";
private static final String OUTPUT_HEADERS = "HTTP/1.1 200 OK\r\n" +
    "Content-Type: text/html\r\n" + 
    "Content-Length: ";
private static final String OUTPUT_END_OF_HEADERS = "\r\n\r\n";

My "session" variable is a Socket object.
