Modifying the Alarm Page

If a visitor triggers block by WAF, the Default block page of WAF is returned by default. You can also configure Custom or Redirection for the block page to be returned as required.

  • Custom: The content of the text/html, text/xml, and application/json pages can be configured on the custom block page to be returned.

  • Redirection: The root domain name of the redirection address must be the same as the currently protected domain name, including a wildcard domain name. For example:

    • If the protected domain name is www.example.com and the port number is 8080, the redirection URL can be set to http://www.example.com:8080/error.html.

    • If the protected wildcard domain name is *.example.com and the port number is 8080, the redirection URL can be set to http://*.example.com:8080/error.html.
