var fs = require(\'fs\');

var options = {
  key: fs.readFileSync(\'test/fixtures/keys/agent2-key.pem\'),
  cert: fs.readFileSync(\'t         


        

Answer 1

response.writeHead(200) sends a response header to the request. The status code is a 3-digit HTTP status code, like 404.

This method must only be called once on a message and it must be called before response.end() is called.

If you call response.write() or response.end() before calling this, the implicit/mutable headers will be calculated and call this function for you.
