Hmm, that kind of generality means you need a very general solution.
I'm not aware of a single solution which would meet your needs.

Had you said that you were using just one or two specific data
formats, then you might consider injecting an extension into the data
that signalled the error (if the format supported that, plus with some
script that could render it in a browser).  That doesn't sound general
enough for you though.

It's well known, but not so oft-encountered AFAIK.  You might try
digging through the IETF HTTP WG archives at
http://lists.w3.org/Archives/Public/ietf-http-wg/

Sorry I couldn't be more help.
