Hi,
Thanks for posting!
From your explain,I think you want to stop the redirect behavior after you get the response data.So I think you can make sence how to use the Winjs.xhr,You can see this code sample:
WinJS.xhr(options).done(
function completed(request) {
// handle completed download.
},
function error(request) {
// handle error conditions.
},
function progress(request) {
// report on progress of download.
});
when you get the requstion,you can add you stop function in completed function,About more detail,You can see this link:

And this sample code:
