Problems uploading large files using IE8

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Uploading large files using Windows 7/IE8

What is the expected output? What do you see instead?
Expect-- successful upload. However, for some users, the upload will timeout. 
Some users report getting redirected to a blank upload page

What version of the product are you using? On what operating system?
r412, Amazon Linus AMI

Please provide any additional information below.

On some computers, the large file uploads works ok, but it fails for others. Is 
there some timeout setting that needs to get adjusted on the client? Anybody 
experience this issue?

got further feedback. For some users on IE, the upload never seems to get 
started.
I'm unable to reproduce the problem on my own computer. However, several people 
have reported the same issue.

Could you get anyone to check if this is a javascript error please?

Thanks for getting back to me.

What would I ask them to look for?  Would you expect an error box to pop
up, or would I ask them to open up the developer console?

thanks in advance

Follow-up:

I suspect that upload issues might be because the folks having problems
don't have a platform that supports plupload/chunking. (IE8 without
silverlight or flash)

I'm waiting to hear back to see if they have silverlight installed.

Question 1: Does this sound like it is on the right track?

Question 2: Is there a way to turn on additional server debugging so that I
can tell what plupload platform/widget the client is using?  (html4,
silverlight, flash, html5?)

Your theory could be correct. The script that handles the actual upload is 
called Plupload.
You can find information about this on http://www.plupload.com/

In the table there, you can see which features are available for each runtime.
html4 is the most basic one and that might be the problem (as you can see, it 
doesn't support chunking).

It's not easy to convince users to change something for a tool's requirements, 
but they shouldn't be using IE anyway :P
They could update to IE10 to see if it fixes the problems, or just start using 
chrome/ff/safari and get an overall better experience everywhere :D

I agree and wish I could just have the users try a different browser,
however the users work in a government setting and are required to use IE8.

In order to debug, I've configured projectsend/plupload to only use the
silverlight widget.
We need chunking support because the files are large (hundreds of megs or
gigs)

What I'm able to reproduce is that the user starts the upload. It will then
jump to a blank "Upload Files" page. In case helpful, the relevant part of
the "blank" html page is below.

Do you have any ideas or pointers of what might cause the aborted upload?

Tiny files can be successfully uploaded.

Will be glad to contribute $$ to this project.

Thanks in advance
Dave

The relevant part of the page is below.
<div id="main">
<h2>Upload files</h2>

</div>

<script type="text/javascript">
$(document).ready(function() {
});
</script>

I know this is an old post but it is something I'm currently experiencing and 
it looks like it has been debugged, at least to some extent, on this post. 
Uploading a file of much size in older IE versions sends the user to a "blank" 
screen. The screen is the upload screen minus any upload capability.. I'd love 
to get this fixed!

I've attached a screenshot of what happens after pressing upload. I was able to 
emulate the issue with BrowserStack implementing Windows XP and IE7.
