Wow, if you could just confirm their existence, that would do fine. So
this resource acts on PUT or DELETE, or POST of a Content-Type other
than "application/x-www-form-urlencoded" or "text/plain"? And it
checks the Content-Type header? And it doesn't require any user
credentials at all? Connectivity is good enough.

Is there any way a browser could tell a request is being sent to a
server behind your firewall, and not a server on the open Internet?

Yes.
