Gone is gone, that's correct. But chances are - the requests being handled by Qt asynchronously - that the request has not yet been sent, and hence I strongly assume that Qt would not process a cancelled request any further.

However I strongly agree with the suggested techniques not to send unnecessary requests in the first place: use timeouts, threshold, caching... you can still cancel requests on top of that when you see fit.
