[Zope] (newbie) External Method continues to run.

[working4aliving]

Hello group,
I'm validating the resolution of url's supplied by customers through the
following...
(testing w/ 7000 records right now)
my DTML method calls a python script that calls a zsql method.  It then
passes the result (row by row)
to a hacked version of webclient.py, and my result gets passed back (1 or
0).  I list the results (failures) in a resulting method.
If I cancel the request (via the stop button on the browser)  my logging
shows the external method contining to run.
Realizing that it's server side, it's not necessarily wrong, but if anyone
can give me an explaination on why (or more like
how to stop it), that'd be great.

Thanks for your help in advance.

Bob
