It really comes down to how you build your application and how it
behaves on a POST. If the application is designed to post something
and come back to the same page, a redirect makes sense after the action
occurs. But then again you have to worry about how to transmit a
mesage back saying the action is done.
Honestly, i think the abuse of the re-direct is due to the commonly
used browser, IE. If you hit back an ugly message comes up warning
the person that it is going to re-post data, if they hit OK and you
protect against it (like the solution you give later in this
thread) your ok, but if they hit cancel, they get an 'Expired
Page'. The redirect avoids that issue.

If the server supports keep-alive connections the client most
likely will use the same connection to make the redirect.

I'm always 100% for thinking things through!
