No. I am just trying to understand how it works and to figure out

Is it required to use define or would let bound variables in start
work also?
George
Yes - let bound variables would work the same.
Thanks,

The values of the parameters are saved in the continuation and
inherited from the thread.

Unless you want to just write a RESTful API, you want
send/suspend/dispatch and you can make any kind of response you want.
The documentation uses response/xexpr but you could put the URL
anywhere you'd like, including sending it in an email or through
carrier pigeon.

Hi Jay,
WRT the database, I was just describing the situation in case anyone had
a better idea than mine.
For my own solution I think the basic question I need answered is how to
generate URLs for 2 differently parameterized calls of the same

Hi George,
The database question is independent of the continuation question and
I'm not sure how to help you solve that problem. However, it sounds
like you are asking if continuations can capture state like "display
sublist 2" or "display sublist 3". They definitely can. Any of the
continuation
