Hi,
I have problem with uploading file to server on IE11 using this plugin: http://blueimp.github.io/jQuery-File-Upload/. I think that this problem is related to IE optimizations around windows authentication. After 2 minutes of idle on the site I try to upload my file. In F12 DevTool I see that my request is pending but, in Fiddler is see 2 requests. First with 0 length (because IE expect to receive 401) with 401 result. The second request is send but after few seconds is canceled. I found two similar cases in the Internet:
