Java Building a Basic WebServer how do i send headers to browser

I'm still learning java and trying to build a basic WebServer using Sockets for now i have the server working and sending output data back to the browser but i'm unsure how to send the headers i thought they were just "\r\n\r\n" from the content body

This is how i'm writing to the browser currently 

Socket socket = socketServer.accept();
System.out.println("Web Request From: "+socket.getInetAddress().toString());

BufferedReader in = new BufferedReader(
     new InputStreamReader(socket.getInputStream())
);
PrintWriter out = new PrintWriter(socket.getOutputStream());
Stirng output = "<!DOCTYPE html><html><body><h1>403 Forbidden</h1></body></html>"
out.write(output, 0, output.lenght());
out.flush();
out.close();

your forced to send the HTTP information first

out.println("HTTP/1.0 200");

is required before any other codes send or the main body

You should take a look at NanoHttpd. Its a one file Web server and its a lot of fun to play with. They are sending headers back, so you should be able to look at their code fairly easily and see what they are doing.

Put the headers in the output string, separated from each other by \r\n and from the main body by \r\n\r\n. Or, with the PrintWriter just print them one by one, an empty line, and then the body.
