Can i use, within the same function: "response.render" and "response.writeHead" options?

response.render('welcome-page.jade', {
    title : 'Welcome user!',
    remoteUser : request.remoteUser,
    id : "identification"
});

// To Write a Cookie
response.writeHead(200, {
  'Set-Cookie': 'mycookie=test',
  'Content-Type': 'text/plain'
});

Is it possible to send also cookies at the client using "response.render", if not how can i resolve this problem?

thanks in advance.
