The protocoll HTTP has content negotiation included. Normally you could use it
via the appropriate http headers. Restlet supports this also via url
parameters, so you are not required to implement it yourself. You could use the
TunnelService of the application for it. See the methods on
Application.getTunnelService.set*() and their javadoc. So it's easy to realize
you proposal 2b.
The TunnelService supports also the content negotiation by file extension, as
you proposed in 1). So, it's all in Restlet, just use it. Use
Application.getTunnelService().setExtensionTunnel(true).
http://www.restlet.org/documentation/1.1/tutorial#part12 shows, how to evaluate
the content negotiation in the server code.
best regards
Stephan
