title: Alternative for QNetworkAccessManager
body: <p>I am drawing map in BB10. The map is divided into tiles. At start user gives a longitude, latitude and zoom level and the map is shown at that co-ordinate. I get a single tile by doing a http request with QNetworkAccessManager. At first 7x5 tiles are downloaded. But the problem is when user starts panning in the screen really fast and continues to do so for sometimes then after user stopped panning the tiles are downloaded with a big delay. Each time user does panning some new tiles are downloaded to show in the screen. Now because user continues panning for awhile there are so many unnecessary network requests with QNetworkAccessManager. And my guess is thats why tile downloading is slow. I tried aborting the QNetoworkReply of the QNetworkAccessManager using abort() method for the unnecessary requests. But still its really slow. Is there any alternate way to achieve what I am trying? Thanks.</p>
