Retrieving cookie from AJAX http redirect

[ghost]

Retrieving a cookie upon successful AJAX entry submission with http redirect (a cookie is set on redirect page - submitted entry) won't update correct value except manual page refresh.

On the redirected page I'm checking a value variable against the retrieving cookie which gives me the expected result but the cookie doesn't give me expected result when I retrieve it somewhere else in other templates. Except page refresh.

Why?

I don't know. Can you post exactly how you're setting and retrieving the cookie (the actual code)?

There is a guest entry submission with AJAX POST and redirect at the end.
The code is stripped-down.

AJAX post

<script type="text/javascript">
$('#add-to-cart').submit(function(ev) {
// Prevent the form from actually submitting
ev.preventDefault();

// Get the post data
var data = $(this).serialize();

// Add the CSRF Token
data[csrfTokenName] = csrfTokenValue;

// Send it to the server
$.post('/', data, function(response, textStatus, jqXHR) {

    if (response.success) {

    // Set countdown and redirection
    var count=2;
    var counter=setInterval(timer, 1000); //1000 will run it every 1 second

	function timer()
	{
	 count=count-1;
	 if (count <= 0)
	   {
              clearInterval(counter);

    //counter ended
    // HTTP redirect
    window.location.replace("{{ siteUrl }}uriA/uriB/{{ token }}");
	   }
	}

	 } else {
	   alert('Hmm..?');
	   }
     });

});
</script>

Redirected page
This page is only reached upon successful entry submission per user's session.
So here I set a simple secure cookie variable.

 {# Set cookie to store cart total. #}
 {% do craft.cookies.setSecure('cartTotal', total) %}

Than
In other template I simply check it if it has any length set like this.

{% if craft.cookies.getSecure('cartTotal')|length %}
    {{ craft.cookies.getSecure('cartTotal') }}
{% else %}
    0
{% endif %}

So when an entry is submitted and I get to redirect page destination the cookie cartTotal is already set in the browser but not retrieving it only upon manual page refresh.
That's the whole story :)

Such rookie mistake. I had cookies variables defined after {% extends "" %} tag which inherited undefined cookie variable before It got set on first page redirect.
