Hey,

What does redirect really do?
I would expect that it sends a 301 || 302 HTTP Code to the new location.
But it doesn't.
When I do:

$this->_redirect("index");

while having URL like http://host/controller/otheraction/key/val

the expected behaviour would be the browser to go to:
http://host/controller/index.

Instead i can see some inner redirect request.
What then is the best way to avoid duplicate FORM posting for instance?
