Referer

When a user clicks on a link on a webpage and the browser takes the user away to the next URL, it sends the new URL a Referer: header in the new request telling it where it came from. That is the referer header. The Referer: is misspelled but that is how it is supposed to be.

With curl you set the referer header with -e or --referer, like this:

curl --referer http://comes-from.example.com https://www.example.com/
