well, just drop packets to those specific sites on TCP port 443. you will have to specific each site individually however. you can only filter https traffic on information contained in the transport layer header or below. everything above that is encrypted.

Why are you blocking sites?

I block sites for access by our school network using squid proxy server and an squid guard.

You have lots of blocking options.
