Hi John, We should indeed provide a better support for this use case. Your suggestions sounds good. I've entered this RFE:

After doing more research on this than I had planned, I found that there's a real problem in Java with trying to use XHTML representations, with DOCTYPE entities, while behind a Proxy server. The Restlet client code kind of masked what the underlying problem was when I wrote the email. The code pasted below fails, for example, when running behind a proxy. I have gotten some client code to work by specifying a custom EntityResolver in the DocumentBuilder, and then wrapping the Document in a DomRepresentation. I wonder if there's a place in Restlet where a client program can either A) specify that the DomBuilder should set the "don't load external DTDs" feature, or B) can send in a custom EntityResolver that returns an empty DTD?
