Matching the referer

Note

The correct English spelling is Referrer. However, the original RFC 2068 contained the spelling Referer, thereby making it the HTTP standard.

A WAF rule with the Custom header condition allows you to match the Referer header in order to detect requests from specific source pages.

Condition: Match the Referer header

For example, proceed as follows to match the referer:

  • ► Select Request as the request method.
  • ► Add the Custom header condition.
  • ► Select the EXACT operator from the drop-down list.
  • ► Enter Referer as the name.
  • ► Enter https://www.youtube.com as the value.
