In my Rails application I am able to upload only up to 1.5GB when using Internet Explorer, but when I use Chrome I am able to upload 10GB without a problem. Why is this? I am running Mongrel as my web server.
Try to look at the http-header:
Content-Length: -1618952669
The value should be the file-size in byte (never a negative-value).
Regarding this Web-Page http://www.motobit.com/help/scptutl/pa98.htm There is a limit within the browser ~2.0GB. Files larger than this may produce an integer-overflow.
