Main features of the Referer header:

  • The Referer contains the absolute or partial address from which the user requested the resource.
  • The Referer allows a server to identify referring pages users come from or where requested resources are used. You can use this data for analytics, logging, optimized caching, and more.
  • When users click a link on any page, the Referer contains the address of the page that includes the link.
  • TheReferer can contain an origin, path, query string, and may not contain URL fragments (i.e #section) or username:password information.
  • The request referrer policy defines the data that can be included in the Referer header.

The usage of the header increases the risk of privacy and security breaches on the website. It’s important to handle it with care. Read more
