route https to specific wan connection

Hello,

Good day! I am currently doing a load balancing between two of my wan
connections using pf based on the rules on this link:
http://www.openbsd.org/faq/pf/pools.html. all tcp, udp and icmp
connections are naturally loadbalnced and i was wondering if there is
a way for me to specify outgoing https (port 443) connections  to a
specific wan connection and not be loadbalanced? some secure sites do
not seem to respond as expected when https is passed through on my
loadbalancer. hoping to hear from anybody. thanks.

Sincerely yours,
Kai
