AsyncUpload (2011.3.1305.40) failing for IE and Chrome (IIS 7.5)

[Peter]

Hi,

I seem unable to upload any large-ish files (around 20mb up) in IE (any version) and Chrome. However, Firefox works fine.

Using the development tools in Internet Explorer, I have noticed that a 404 error occurs. I have run though the following steps:

Unfortunately,  This hasn't help.

We are currently running under IIS 7.5

Hi Peter,

The issue is most probably caused by the DisablePlugins="true" property that is set. Please try to remove it and upload the file again. You can also set the Chucnk size as it is shown in out on-line demo where this functionality is described.

Hope this will help you solve the issue.
