To configure URL filtering such that users receive a warning when they access a specific website (e.g.,
http://www.badadultsite.com) and have the option to continue to the site, the engineer needs to perform the following actions:
* Configure an access control rule:
* Create a URL object for http://www.badadultsite.com.
* Set the action for this URL object to "Interactive Block," which prompts the user with a warning and allows them to proceed if they choose to.
* Set the Interactive Block Response Page:
* Navigate to the HTTP Responses tab in the access control policy editor.
* Set the Interactive Block Response Page to "System-provided" to ensure that users see the default warning page provided by Cisco Secure Firewall Management Center.
These actions ensure that only the specified website triggers an interactive block, while other websites are not blocked.
