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.
