Hello Roy,

Are you saying that if a file foo.html is put as
      text/html; charset=UTF-8
but the server has a configuration for .html to
use text/html; charset=iso-8859-1, then the correct thing for the
server is to serve that file as text/html; charset=iso-8859-1, even
if that is observably wrong?

Why shouldn't the server just update the configuration?
Is there anything in the HTTP spec that says that server
configuration is more important than the metadata attached
to a document?
