OK. As promised. Here is the code that I believe is required to
support what you want. Be aware that I have not actually used this nor
tested this, but did double check everything against eclipse as I went.
Two classes, and a contribution to the Ioc Module of your choosing.
Then whenever you return a PageRenderResult object, it will render that
page on the serverside and return it, without having the client-side do
a redirect.
Give it a shot if you want, and let us know how it goes. You can add
this to the JIRA.
