Hi Jeff,
No I have not answered that question. In fact that is a VERY good question. See, if you check out this link (which is the list of requirements in the CURRENT documentation):
https://openacs.org/doc/current/individual-programs.html
then scroll down to the part where it says "Web Server", then you will see:
AOLserver 3.3oacs1, REQUIRED. Â Mat Kovach's source...
If that wasn't there, then I would have gone a different route.
