Form Post Redirect to Form Get

[GiftsForYouBiz]

Probably not a new concept, but a friend of mine developed a way that our form posts will 'redirect' (via a Java Temporary Redirect [307?]) back to a page that presents Get data, so that if the user hits the back button, the Get data is what's retrieved from the browser history, not the Post page/data.

So, I was just curious:

1. How much thought should be put into making form posts come back to the browser as Get information, so that the back button can still be used, and so that re-posts aren't an issue?

2. How much thought have developers put into this method of form posts?

3. Can anyone say with any certainty that web surfers care one way or another, if at all? Or does it happen so infrequently that no one even thinks much about it?

Being I've not heard much about this train of thought in the 8+ years I've been developing, I thought his way of doing this was innovative. But he said its natural and that he'd be surprised if most developers weren't doing this. Thus, my curiosity and subsequent questions.[/google]
