David Wright, I knew when posting that I left wiggle room in the area of RAM and the number of users who are really using the site at once. For the record, let's say RAM is not an issue. We can keep the session vars to a minimum.
I was trying to get a response for the Practical Session Limits in the environment I described. I guess another approach is to try to determine the bottle-necks. What is the most limiting factor, then the next, etc. I'm expecting that 4D/A4D will be the first bottle-neck. If that is the case, then it may be possible to have a web server in front of 4D/A4D that load-balances among several 4D Client/A4D web servers. Who is doing this http server architecture that I can point to and say "Look here..." If someone is doing this, are they running multiple 4D/A4D web clients on single a multi-processor box? I really wonder how this scenario can be load balanced managed by front-end web server (probably using running/repeating sequence of IP ports [8080;then 8081;8082...8089;then 8080;etc..]). I need a scale-ability answer to point to and say.... (you get the idea).

We have sites with 10,000-plus users, and we encourage them to log in using reminder emails. We send all the emails in one burst, and even then our A4D-based system is comfortably within its capabilities. You could stagger reminders. We tend to see the most sessions open when Google or someone is harvesting! As far as I know the number of session items is not too significant, but you need to be sure that the amount of RAM they add up to is within your hardware's specification. Bear in mind I'm not a great expert!
