A redirect with spring.js not work as expected

I use spring.js with tiles in my web app. I found there's a very strong assumption on redirect.

If my outcome is in same page, is only reloaded the fragment.
But if I use spring.js and tiles.
Image I have a 3 step page, and i always have ajax load, so my page name in the url never change. When I call redirect I want redirect, not make a partial load, otherwise I specified the fragment.

I propose this patch in javascript.
