There might be, but I haven't heard of it. What your describing actually makes sense. A redirect implies the page is now elsewhere. So why save it in the history? That is...

GET /some-page (in history)
GET /some-old-url (results in redirect to /some-new-url)
GET /some-new-url (in history)

Why, normally would you want to see that second request in your browser history?

I don't know how you have your app setup, but instead of redirecting, what about sending back an almost empty page containing just enough javascript or meta-refresh to take you to the next page.
