Question

How do I find the a referring sites URL in node?

I\'m using express, would I find this in the headers on connect or something?

Thanks!

Answer 1

If you mean how do you get it when running an express server, then it's done using the header method on your request:

req.header('Referer');
// => "http://google.com"

Answer 2

In express 4.x:

req.get('Referrer')

This will also check both spellings of referrer so you do not have to do:

 req.headers.referrer || req.headers.referer

Here is the documentation
