To make an iframe redirect with cookies, you can use JavaScript to set a cookie on the parent page and then read that cookie in the iframe to determine the redirect URL. Here's a step-by-step guide on how to do this:

  1. Set a cookie on the parent page with the redirect URL:
1
document.cookie = "redirectUrl=https://www.example.com";


  1. In the iframe, read the cookie and redirect to the specified URL:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
// Function to get cookie value by name
function getCookie(name) {
    var value = "; " + document.cookie;
    var parts = value.split("; " + name + "=");
    if (parts.length == 2) return parts.pop().split(";").shift();
}

// Get the redirect URL from the cookie
var redirectUrl = getCookie("redirectUrl");

// Redirect the iframe to the specified URL
if (redirectUrl) {
    window.location.href = redirectUrl;
}


  1. Embed the iframe in the parent page and include the script to read the cookie and perform the redirect:
1
2
3
4
<iframe src="your-iframe-url" id="myIframe"></iframe>
<script>
    // Your script to read the cookie and redirect
</script>


By following these steps, you can use cookies to redirect an iframe to a specified URL. Keep in mind that the same-origin policy may restrict your ability to successfully read cookies across different domain or subdomain boundaries.
