And if they don't match what does it use?  Is this behavior supported
in any of the RFCs regarding http?  Such as RFC 2616.

And does that only apply to pdfs (for some odd reason) or also to .doc,
.jpg, .gif, .xls and so on?

We have all seen people complain that other browsers are broken
because their web pages show fine in IE but shows the source in other
browsers.  Of course it's because their webserver is set to send
text/plain for .html files.  I'm just wondering if this is the same
issue or not.

I would have hoped that it was fixed in IE7 considering how long its
been a problem.
