Hypertext Transfer Protocol Secure (HTTPS) is a combination of the Hypertext Transfer Protocol with the SSL/TLS protocol to provide encryption and secure (website security testing) identification of the server. It uses port 443. HTTPS connections are often used for payment transactions on the World Wide Web and for sensitive transactions in corporate information systems.
As more and more websites provide both HTTP and HTTPS access. For example, facebook.com can be access both from "http://www.facebook.com" and "https://www.facebook.com". So you can not block facebook completely until both http and https are blocked. However, HTTPS are widely used in payment transactions, web email authentication ..., so block all HTTPS traffic will not be a good choice.
