Node.js server just keeps loading with no result.

Question

I have been trying to get my server to work but when I send post data it just keeps loading and no results are given. Here is my noen.js file.

var http = require('http');
var url = require('url');

// Configure our HTTP server to respond with Hello World to all requests.
var server = http.createServer(function (request, response) {
  var queryData = url.parse(request.url, true).query;
  response.writeHead(200, {"Content-Type": "text/plain"});

  if (queryData.name) {
    // user told us their name in the GET request, ex: http://host:8000/?name=Tom
    var exec = require('child_process').exec;
    function puts(error, stdout, stderr) {sys.puts(stdout)}
    exec ("casperjs test.js " + queryData.name + '\n');

  } else {
response.end("Contact Admin - Not Working\n");
  }
});

// Listen on port 8000, IP defaults to 127.0.0.1
server.listen(1213);

Can anyone help me fix this? When I go to

127.0.0.1:8000/?name=tom 

I get no response the page just goes into a long loading loop

There is no response.end in case if is true so then response "never" ends. write at bottom of the if

response.end("something");

And you will get the response;

For get the output of the process to the response:

    });

  } else {

  }
});

// Listen on port 8000, IP defaults to 127.0.0.1
server.listen(1213);
