Referer

Address of the page that made the request

What the Referer header does

Referer (a historical misspelling of 'referrer') is the URL of the page that linked to or triggered the request — useful for analytics and logging. How much of it is sent is governed by the Referrer-Policy header, since full URLs can leak sensitive data.

Example

Referer: https://google.com/

Where it's used
