Downloading a file from our website's cart to a Windows 2000 Pro desktop
running latest IE 6 is slow and takes 15 seconds

Downloading the same file to a Windows XP box running IE 6, a Windows
Pro box running Mozilla, and a Mac OSX running safari takes approx 1
second. Linux / Apache is fast to all clients.

Spoke with Microsoft, we put a 1M file in a virtual directory on IIS.
It downloaded in approx 1 second to Windows Pro / IE6. So they say "not
our problem" talk to the Tomcat / mod_jk users.

But, When I take IIS/mod_jk out of the picture, and go directly to
Tomcat on 8080 the download is fast on the Windows Pro / IE6. I still
think it's a MS issue anyone know why the download is slow between IIS 6
and Windows 2000 Pro / IE6 and fast to all other clients.

Confounded. Any suggestions???? Thanks!!
