How do you cancel an html cfgrid request after it is sent.

["BrianO" <webforumsuser@xxxxxxxxxxxxxx>]

I was testing a cfgrid and because of an error in the code it took a long time 
to respond so I hit the IE6 (I know, but that is my customer's call) stop 
button and tried to submit the grid request a second and then a third time. I 
received 3 error messages, one for each of the threads. I fixed my bug and know 
I'm dealing now in the asynchronous world of AJAX, but how do I programatically 
allow a user to cancel a request for data from a html-based cfgrid?
