Opening A (Binary) File With An Unknown Extension (.MSG, .CAD) Using IE Opens File In Browser Instead Of Prompting User To Download (Doc ID 1373257.1)

When downloading the weblayout copy of a file with an unknown extension (.msg, .123) in Internet Explorer, the browser opens the file as plain text. For binary files, this will results in a page with unreadable content (garbage characters).

Downloading the same file in Mozilla/Firefox correctly prompts the end-user to download the file to disk.

A TCP/IP trace shows that the content-type (mime-type) is not passed to the browser in the HTTP response header:
