James,
I deleted my earlier post as I had misread your message.
Yes you can do this with Pound:
1. One Pound instance (p1) handles requests for www.mydomain1.com another (p2) for www.mydomain2.com. They handle both HTTP and HTTPS connections.
2. Both Pound instances proxy the same internal aolserver. All external requests are forwarded to aolserver as HTTP requests. Aolserver uses the header in the request to map the request to the appropriate sub-site.
3. Pound includes 'X-SSL-Request: true' to HTTPS requests forwarded to aolserver. Aolserver uses this information to detect HTTPS connections. I can provide modifications to the request processor to make this transparent to OpenACS.
There is no need to setup an internal DNS.
