URL filtering response pages notify users when access to a requested URL has been restricted. Access may be restricted if a site belongs to a category that has been configured with a block, continue, or override action or credential submissions to the site or category has been blocked. If a user doesn't have the strictest safe search settings configured for a search engine and a Security policy rule enforces safe search, access is also restricted. Five predefined response pages exist to account for these reasons. Some response pages outright block access, while others allow conditional access. For example, if the URL Filtering Continue and Override Page or Anti Phishing Continue Page appears, users can click Continue to enter the site (unless URL Admin Override is enabled).

In general, the response pages state why the page cannot be accessed and list the user, URL, and URL category. However, you can customize the content and appearance of the response pages. For example, you can change the notification message, link to your acceptable use policy, or add corporate branding.
