non squid parent not routing SSL

Hi,

ill make this as short and accurate as possible. We have a squid server that
has a parent that is a non squid server, in fact it is a firewall with smart
proxying enabled. The firewall is enabled on both 443 and 80. What we want
to do is have all port 80 traffic go via port 80 and all SSL traffic go via
port 443, is this possible with squid?. what directives should i use.

Thanks in Advance
