使用jQuery Ajax的Android浏览器问题以及使用appcache时的问题

we are having a problem with the built in browser on Android 4.0, 4.1 and 4.2 (we haven't got anything lower to test on). The problem is that the ajax call will work perfectly on first load, you can press the run Ajax button as many times as you like and it will be fine. You can disconnect from the internet and it will work properly. But if you exit (FULLY, make sure its not just running in the background) the browser then relaunch it, it will fail on load and on button press. It doesn't matter if you are on-line or off-line. The error that is been returned from the ajax call is "Error" with status = 0 and readyState = 0.we are having a problem with the built in brows
