Well, maybe :-)
I know nothing about ASP, but if I were trying to do this in a
servlet/JSP environment, I'd consider:
1) frames -- launch this long-running process from a framed page
where there's a separate "control panel" to hold the giant red
STOP button :-)
2) server push -- haven't seen this used in a long time, but that
would allow you to deliver a preliminary ("please wait...") page
that could also contain a STOP button. Unless terminated by the
button push, the process would then overwrite the wait page with
the query results.
In either case, pressing the STOP button requests a process to set
the variable your `do..` loop is testing for and return the "what
now?" page.
Also, neither of these approaches depends on JavaScript.
FWIW!
