The following un-cached protocols are prioritised on the network: HTTP (in certain cases HTTP is not cached due to website incompatibilities), HTTPS, FTP, Mail (POP3, SMTP and IMAP), SSH and TELNET. Any protocol not mentioned above will receive a lower priority on the network.
Considering that 443 is the standard ssl port is should not be shaped, but could be shaped slightly. SSL traffic is theoretically not as important (ie. would not have as high a priority) as http/smtp/pop.
