Yes, CF is supported on IIS.

Great suggestion, thanks! At first when I used this suggestion, the
header issue got worse - the headers were printed out in the source, and
the page must have been served at text instead of HTML cause all I saw
was the source. Sent a ticket in to the host, who said there was nothing
wrong. And now the problem is gone. Hmmm... :) I wish I had an
explanation for why this was happening since I'd never seen anything
like this before, but oh well, it's gone, the client is happy, so I'm happy.
