How large can a single cookie be? The answer is depending what is the Web browser your visitor is using. Each browser has its own limit:
- Internet Explorere (IE): about 3904 bytes
- Mozilla FireFox: about 3136 bytess
If you want to test this limit, copy this sample script, huge_cookies.php, to your Web server:
<?php
if (isset($_COOKIE["HomeSite"])) {
$value = $_COOKIE["HomeSite"];
} else {
$value = "";
}
$value .= "http://dev.FYICenter.com/faq/php";
setcookie("HomeSite", $value);
print("<pre>\n");
print("Large cookie set with ".strlen($value)." characters.\n");
print("</pre>\n");
?>
Open your browser to this page for first time, you will see:
Large cookie set with 32 characters.
Click the refresh button, you will see:
Large cookie set with 64 characters.
Keep clicking the refresh button, you will see the limit of your browser.
