header is text/html, then the client (browser) knows that it is HTML
and presents it accordingly. 

I've never run into the problem you describe with .plt files, and it
may be that I never installed the CAD application, but I would expect
that metadata associated with the file would indicate that it's not an

I had thought a generic media type like application/octet-stream would
be nice because it would at least allow downloading the file with a
single click. In fact, that's the behavior I expected, not having the
installer launch automatically. (This was under Windows, but even on my
PowerBook, clicking on the .plt files automatically launches the installer.)
