Node.js : How can I Output Data Before I end the Response?
var http = require('http');

http.createServer(function(request, response){
   // Write Headers
   response.writeHead(200);

   // Write Hello World!
   response.write("Hello World!");

   // End Response after 5 seconds
   setTimeout(function(){
        response.end();
   }, 5000);

}).listen(8000);

// Write Headers
response.writeHead(200, {'Content-Type': 'text/plain'});
