I\'m currently working on a purely HTML and JavaScript driven web app that uses CORS for consuming a remote web service but currently having trouble with IE 11 making a GET
i'm not sure, maybe it's caching, try to set property "cache: false"
otherwise, you can also try add a datetime at the end of your url, so you have everytime a different url and IE won't cache
url +""+ (new Date()).getTime()
