Clearing Post Data with IE - PHP

Using "Pragma: private" instead of no-cache would elminate that message
about cache expired and asking if you want to resubmit. However, based on
your questions. It's not the answer you're looking for. So, there is a
better way around. Just do Webpage #1 for form and submit it to Webpage #2
for processing the form like the database or session for example, then use
the header("Location: ****") to get to Webpage #3 where you can display the
result. That way, Webpage #2 was never reached to the web-browser and was
never cached.

After you've finished all of the processing, just do:

header( 'location: ' . $_SERVER['PHP_SELF'] );
exit();

I tried using the Header('location: ....') but it seems the posted data
follows the redirection
Im going from my main page to a processing page then back to my main page.
i printed $_POST on the main page and it still has the values that were
originally posted to the
processing page. Also after the redirection the address in the address bar
is that of the processing page

Here is some code to help explain:

--index.php
print_r($_POST);
....
echo "<form action='poll.php' method='POST'>";
echo "<input name='poll_id' type='hidden' value='$poll_id'>\n";
echo "<input name='calling' type='hidden' value='" .
$_SERVER['PHP_SELF'] . "'>\n";
foreach($poll->choices as $id => $choice) {
echo "<input name='poll_choice' type='radio' value=$choice->id
>$choice->choice<br>\n";
}
echo "<input type='submit' value='submit'>";
echo "</form>";


--poll.php
$poll_id = $_POST['poll_id'];
$poll_choice = $_POST['poll_choice'];
$calling = $_POST['calling'];

if (isset($poll_id)) {
unset($_POST);
Header("Location: $calling");
exit();
}


When poll.php loads up index.php the Posted data is still there.
