Upload file functionality fails randomly

I've got a web application that includes a file upload page. It was upgraded
from v1.1 to 2. We haven't converted the page to use the newer file upload
control, though. We're using the encType="multipart/form-data" attribute on
the form element. Everything seems to work with no problems for most users.

Occasionally, though, it's like the server picks on some poor sap and
doesn't pass any of the uploads through. Other individuals can upload during
this same period. The individuals affected seem to change. It's not a
specific machine or person. But, there seems to always be one person that has
trouble uploading.

I've modified the MaxRequestLength property for the specific web page to
accept requests up to 40MB. The files are nowhere near that size (40 - 80
KB). And, like I said, it works for others during this same time period.

We're running this application on a Windows 2003 server standard edition
with SP1. The machine has 3GB of available memory.

No exceptions are thrown. No entries are getting added to the event log,
either. We get a lot expired auth tickets (forms authentication). But, the
Request.Files.Count is indicating zero files uploaded.

I've done a cursory search and have only been able to

Hi Martin,

Does this issue occur before migrating to ASP.NET 2.0?

Would you please show some code?

Also, please use Fiddler (http://www.fiddlertool.com/) to trace the http
request/response and post some failing uploading request's log here. Thanks.
Sincerely,
Walter Wang (wa****@online.microsoft.com, remove 'online.')
