Note Submitter: jamief at qubesoft dot com ---- If you specify a filename with a number in a content disposition header, Internet Explorer 6 tries to be clever with it, and plays with the filename to try to version it. However, if you don't specify a filename, it will happily use the filename in the URL, and will NOT try to version it. Useful if you have filenames like Q-1.1-win32-bin.msi and you don't want them to end up as Q-1(1).1-win32-bin.msi. Unfortunately Firefox performs similar mangling regardless of how it received the filename.
