Uploadify and HTTP 401. Why doesn't it work sequentially?

Using the Uploadify plugin using jQuery and SWF. Some web servers work, and some do not. It seems that when you try to download the HTTP 401 autoresponder is not authorized. May be related to SWF. In Fiddler, when it doesn’t work, it looks like this Proxy-Support: Session-Based-Authentication, but when it works, we don’t get session-based authentication. Is this a network routing problem? Problem with proxy? Any suggestions for fixing

I recently ran into this problem.

In my case, I used IIS with Windows Authentication enabled (without anonymous access). This prevented the download of Flash files due to the fact that it started the download process as a separate session without authentication. To allow, I only allowed anonymous access to the handler files, and loading now works just fine.
