I downloaded 'AjaxUploader 3.0 2014-03-13' to solve our compatibility issues with IE 11.

I am testing wIth a net_cs/samples/simple-upload.aspx

When I upload a file in IE11 standards mode, the uploaders stalls about 19%.

I can still cancel the upload. 

When I add my domain to the IE11 Compatibility View Settings, the upload works without a problem.

I have tested this on two different machines. 

Hi,

I can not reproduce this issue, can you try on http://www.ajaxuploader.com/Demo/Large-File-Upload.aspx? Does the demo gets the same problem with your IE11?

Regards,

Ken 

 No, I cannot reproduce it on the demo website.

However, it happens locally on three different environments: developer machine, test server and production server. 

Hi mmbderksen,

Does it only happens on IE11? Does the site under load balancing/web farm environment? Can you deploy the demo on another pc to try again?

Regards,

Ken 

I have made this url below available on our test server.

If I add the site to  compatibility view settings, upload works fine.

I am testing wit the simple upload with progress. 

Please, ignore the certificate warrnings .

I am experiencing similar problems with IE 11 users.

I have a multiple upload page. Today the user was uploading 3 files.

The upload failed on the first upload. The UploadCompleted was triggered in the code behind - but I see no evidence of the file arriving.

The first time the user got this error

SERVER SIDE EXCEPTION: failed to download 1094252-v1.wmv

System Exception: Invalid form data,last bounday not found:\xOD\xOA

at CuteWebUI.a.a(Http_Context A_0, HttpWorkerRequest A_1, etc etc

(I can email you the jpg screen capture if needed) 

It has been working flawlessly for months for Chrome users

I just saw that you released an update for IE11.

I have downloaded and installed that. Will re-post if problem persists
