Hi Simon, Resource#getPreferredVariant() is exactly what you what to use. It will indicate you the best variant for the current request. Then you can look at the variant's media type to build your redirect URI.
Of course, you first need to declare the list of all available variants (you need to know them in order to negotiate anything).

The reason is that the specific resources are on different (unrelated) domains and I don't want to republish the other domain's data but instead tell the client where it is. Using conneg would also mean that the representations have certain properties in common with the generic resource (the one I'm doing the conneg from) but I don't want this relatedness, it would lead to copyright problems and whatnot. Anyway, I'm having difficulties implementing that. My idea so far is that I have a Restlet for the generic resource which, in the handle method, inspects the different accept values available in the ClientInfo object (Restlet.getClientInfo()), decides which resource is most appropriate, gets the URI for that resource and then calls response.redirectSeeOther(uri); Then I would attach the Restlet for the generic resource as well as the specific Resource classes to a router and would be done. The problem is the deciding bit. I don't want to re-implement all the conneg logic. Is there a way to use what's there already? I'd rather use a Resource class than a raw Restlet. And if not, where would I find the code for how the conneg logic is implemented at the moment? Resource.getPreferredVariant()? Maybe I can copy the needed bits from there before starting from scratch. :-) Thanks, Simon
