I hesitate here because the Web site sends the proper
file type:

  Content-Type: text/plain; charset=utf-8

If IE does not understand that the file is plain text encoded in
UTF-8, it is broken.

Using the file extension to find its type is both non-standard (why
".txt" instead of ".text"? Where is the registry of file extensions?)
and quite old-fashioned.
