Modifying the Alarm Page¶
If a visitor is blocked 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.
Note
If you have enabled enterprise projects, ensure that you have all operation permissions for the project where your WAF instance locates. Then, you can select the enterprise project from the Enterprise Project drop-down list and customize alarm pages for the domain names.

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