Simon,

I did something similar a few weeks ago by launching a separate window when the long process start running. This separate window starts its own connection and when users click the CANCEL button I just close this separate window (closing the connection as well.)

In my case the long running request was a call to a web service, not a stored procedure, but the logic might apply to you as well.
