Well, if you're using WicketFilter, then you can just write your own
servlet. If WicketFilter doesn't think it's responsible for the
request, it'll let it flow through. So, you could just code this
using Servlets anyway.
Wouldn't extending WebResource and using ResourceLink be the way to do
this within Wicket, though? Looking at the API, that seems like the
way to go.
