  3. Click Save Changes.

Redirecting the Response to a Specified URL

  1. From the SECURITY POLICIES > Action Policy page, click Edit next to the Attack Action to be modified.
  2. Set the Deny Response parameter to Redirect.
  3. Add the URL the client should be redirected to if the request is denied.

Applying a Custom Response Page to a Specific Action

  1. From the ADVANCED > Libraries, Response Pages section, click Add to create a Custom Response Page.
  2. From the SECURITY POLICIES > Action Policy page, click Edit next to the Attack Action to be modified.
