Fellow Monasterians

I'm stumped trying to create a session, add a param, and then redirect all at once. Understandably I keep getting a "Status: 302 Moved Location" error as it has to print the header twice.

A note on what I'm trying to accomplish: 1) check to see if a session has been created, if so, 2) retrieve the values for an array, if not 3) create the session, but in both cases 4) push a value to my array and store it back in the session, and finally 5) redirect to the page. Here's the code:

my $current_page = shift;
my @pages;
my $session = new CGI::Session();

if ( $session->param('authorized_pages') ) {
   @pages = $session->param('authorized_pages');
   
} else {
   print $session->header();
}

push @pages, $current_page;
$session->param( 'authorized_pages' => \@pages );
print redirect("/?page=$current_page");

I tried:

print $session->header(-location => "/?page=$current_page");

but I couldn't add my param, of course.

So, what am I not seeing or understanding?
