If the client sends the wrong type, then the client is the problem. I don't
see a big need to support bad clients. That will just continue to ensure
that they will always use bad behavior.

Take the supplied Content-Type and store it.

mod_dav_fs ignores it, but don't take that as gospel. That is mostly for
performance reasons -- where would we put it? and how would we fetch it
again? I chose to use Apache's builtin mime type determination instead.

This kind of stuff is in mod_mime and mod_mime_magic, I believe. Since those
functions are in a module rather than Apache "proper", there isn't really a
way to call them.

No, I don't think so. If you can identify a function within Apache to do the
file-extension to type mapping (if you go that route), then we can see about
getting it moved to an appropriate spot and exported from Apache.
