Upload Indicator Incorrectly Renders the Progress


Product Progress® Kendo UI® Upload for jQuery
Operating System Windows 10 64bit


The jQuery Upload progress indicator incorrectly renders the progress of the upload.


When working in Internet Explorer version 10 or 11 with Windows authentication, the upload progress indicator can go over 100% or freeze but does not indicate that the request is complete. The issue is not related to Kendo UI and is caused by a bug in Internet Explorer which can be observed with any FormData XMLHttpRequest. The problem seems to occur only when accessing a web server on localhost.


Deploy the application on a remote web server or disable asynchronous uploads.
