Right,

Seems reasonable. I'd say what you should do is create a session on
the first access and store some marker in the session on the second
access.
The code can then establish whether the session contains your marker
to work out whether the request is within range.
Another way to do it would be to return a cookie on the first
response. With most scenarios this would be exactly the same as the
session.

No. Absolutely not. NEVER use SingleThreadModel. Go back through the
archives to establish why not (this has been discussed many, many
times).
>My OOD isn't too hot either!
Keep at it and it'll get better.
