Get original URL referer with PHP

Store it either in a cookie (if it's acceptable for your situation), or in a session variable.

<?php

  session_start();

  if (!isset($_SESSION["origURL"]))
    $_SESSION["origURL"] = $_SERVER["HTTP_REFERER"];
?>

$_SERVER['HTTP_REFERER']; to get the referer Url. It works as expected until the user clicks another page and the referer changes to the last page.
