通过 SSL。在 Chrome/Firefox 中工作，但对 Opera/Safari/IE 的 sessionTestVariable 显示空值:
<? // https://mydomain.com/setSession.php
session_cache_limiter( 'nocache' );
session_set_cookie_params("899", "/", ".mydomain.com");
session_start();
unset($_SESSION['sessionTestVariable']);
// Set sessionTestVariable
$_SESSION['sessionTestVariable'] = "some string";
header("Cache-Control: no-cache, must-revalidate, post-check=3600, pre-check=3600"); // CacheBusting
header("Location: http://mydomain2.com/testSession.php");
exit; // this *should* fix the problem but does not
?>
////////////
<? // http://mydomain2.com/testSession.php
echo "Testing to see if we can trigger the session from mydomain.com";
echo "<script type=\"text/javascript\" src=\"https://mydomain.com/triggerCookie.php\">";
?>
////////////
<? // https://mydomain.com/triggerCookie.php
session_cache_limiter( 'nocache' );
session_set_cookie_params("899", "/", ".mydomain.com");
session_start();
// Set sessionTestVariable
echo "alert('session: " . $_SESSION['sessionTestVariable'] . "');";
session_destroy();
?>
最佳答案
我能够解决这个问题。答案在于称为 P3P 的协议(protocol)。
我加了
header('P3P:CP="IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"');
就在
session_start()
有效!
