    -<note important>When a request for a restricted resource is detected, the SSG sends an HTTP redirect to a placeholder page to the subscriber (IP1). A TCP RST packet is sent to the restricted resource (IP2) to drop the connection. Blocking (HTTPS) and redirecting (HTTP) occurs because the SSG responds to the request from IP1 faster than IP2.</note>+<note important>When a request for a restricted resource is detected, the SSG sends an HTTP redirect to a placeholder page to the subscriber (IP1).\\ A TCP RST packet is sent to the restricted resource (IP2) to drop the connection.
