I've used a method that essentially combines (with modifications) the two
ideas you've already been presented with.
If there is $_POST data present, I put it into the $_SESSION variable,
something like:
$_SESSION[ 'post_data' ] = $_POST;
and then I force a reload of the page.
Now, if the page loads WITHOUT $_POST data, but WITH $_SESSION[
'post_data' ] present, then I do the processing and null out $_SESSION[
'post_data' ].
I don't know if this is foolproof (I suspect it's not), but it's been quite
effective where I've used it.
