How do we set additional headers?

[jamieburchell]

Looking at the code and examples and I can't see how I could set additional headers for cache control. It's not possible to extend the Servlet class and overwrite the default headers method as the class is final.

As referenced in my response to #6, this would need a custom Resource implementation, specifically the getAdditionalHeaders() method.

I will close this issue in favour of #6 because they are closely related, and I think it will be more helpful to talk about specifics if there are any follow-ups :-)
