IE caches ajax request as default. Never saw/recongized this in
Chrome/Firefox. I think most of the jax-rs resources and typerender
don't want to cache the ajax requests - so default should be no cache.
Makes no sense for me to update all jaxrs resources and typrender
(there a lot of in our projects)

What do you mean with serializer: MessageBodyWriter or somewhere in triaxrs?
