Forum OpenACS Development: Re: Issues with site-wide SSL configuration
You might consider the following options:
1) experiment with the various nsopenssl updates [1,2] or try to contact scott goodwin
2) upgrade from AOLserver to NaviServer, and use current OpenACS sources as a running documentation, what changes are needed (when i added the first NaviServer support to OpenACS more than 10 years ago, i remember, it was not much work)
3) use a reverse proxy such as nginx  for ssl/tls offloading
If you not want to invest effort in this application, (3) is probably the easiest step.
Option (1) is where we are today and we plan to run some tests this week. If the issues persist, I think we will try option (3) next as we want to get this done as soon as possible.
We had also considered moving this to NaviServer but were afraid it would be an insurmountable task. It's encouraging to hear that it is not too much work
The link  shows the changes in packages/acs-* in chronological order (starting 13 years ago) to give you a glimpse what's needed.
