There are two potential ways to do this.  It depends if you have a dedicated public IP address you can assign to your internal server or not.  The first part is if you do.  The second part is if you only have a single IP assigned to your public interface on your PIX (assigned by dhcp maybe from your ISP)

you need to do track down the following data first:

Server Private IP - ex. 10.1.1.100
Server Public IP - ex. 1.2.3.4
ACL name (if one exists) assigned to outside interface allowing traffic in - ex. outside_in

then you add the access-list entry you need

access-list outside_in line 1 permit tcp any host 1.2.3.4 eq 443

this adds the new entry at line 1 (top of the access-list) and permits any host to get access to the public IP on port 443/TCP.

then you create the translation.  I'm going to assume the standard names for your interfaces.  outside and inside.

static (inside,outside) 1.2.3.4 10.1.1.100 dns

this will translate anything coming to 1.2.3.4 to 10.1.1.100 as it comes from the outside side of the asa and flows to the real server.  the 'dns' keyword is so that if hosts are inside your network that want to communicate using the public domain name, the asa will "doctor" the dns reply so the internal host goes directly to the internal server

the second way is if you have only a single interface ip

access-list outside_in line 1 permit tcp any interface outside eq 443
static (inside,outside) tcp interface 443 10.1.1.100 443

there is no 'dns' on this static translation because its a PAT and not a NAT

hope this helps
