How it works...

Reading headers in Express is done using the get or header method on a request object. You can also use req.headers to find a dictionary of all the headers passed along in the request:

req.get('user-agent');req.header('user-agent');req.headers['user-agent'];

Sending headers in Express is done by providing a header name and value to the set or header method of a response object. You can also set multiple headers at once by providing a dictionary. Some common response headers, such as Content-Type, also have aliases available on the response object:

res.set('Content-Type', 'text/html');res.set({  'Content-Type': 'text/html',  'X-Frame-Options': 'SAMEORIGIN'});res.header('Content-Type', 'text/html');res.contentType('text/html' ...
