User cancel feature

----------ONLY HEADERS ABOVE THIS LINE------------

I am trying to figure out how in libwww one can cancel a fetch request 
(like clicking on the Globe in Mosaic). I assumed there would be 
someway to do this through the HTAlert module but could not find any.
I was thinking of something along the lines of having a user event
set a global variable that is checked at progress time in the HTAlert
module and if true, the request is cancelled.
