Because of the nature of https connections it's often times not possible to send a block page to the end user after an HTTPS connection has been made with the website. The browser will not honor a TCP redirect from a secure website (the https site) to an unsecured website (the block page). The block page is only successfully delivered if the filter is able to send the redirect before the browser complete the TCP handshake with the website.
Instead of the Web Filter block page you will see an error message which will vary depending on the browser type.
