We recently upgrade to Ajax Uploader v 11.0.16.2, but we found a problem with uploading a larger file( greater than 32 MB. Smaller file works fine), the Ajax uploader stuck at the very beginning and eventually time out. It only happen with IIS7. With IIS6 or Visual studio development server every thing work fine.

The system configuration is as following
OS: Windows Server 2008 R2 ( Windows 7 too );
IIS: V7.x
.Net version : V2.0
App pool : both 32bit and 64bit.
browser: FireFox v22, IE v10.

the following is an AJAX session we capture during debugging, it continues until time out

Hi,

This has to do with your IIS 7 request filtering settings. See here for more details:
