I have managed to build a first CGI application, using web broker. It is
managed by IIS.
Starting with the intro's at www.maltus.com I got to a working prototype in
a few days. Very impressive Delphi functionality!

The app is for use in schools (conjugation of verbs in Dutch). And it keeps
a score. This leads to an interesting problem. If the user picks a wrong
answer, he can just step back using the browser back-button and re-enter.
That implies that keeping the score via query fields will not work. So, I
decided to maintain state information on the server. The content of the
information record is trivial: just a string. But writing it somewhere is a
problem. For starters I wanted to just write a file with a name derived from
the remote host/IP address. There is then little chance of conflict. But
under IIS the app appears not to be allowed to write anywhere. Not in the
wwwroot tree; neither on C:\. A sensible security precaution.

Will I have to install a database or are there other suggestions to cope
with this?
Your help will be appreciated.
