Sub domain sessions via ajax requests?

Question

PHP

So I started to analyze this topic, I found an interesting problem:
I set the parameters in .htacess

php_value session.cookie_domain .portal.my<br/>
&lt;IfModule mod_headers.c&gt;<br/>
Header set Access-Control-Allow-Origin &quot;*&quot;<br/>
&lt;/IfModule &gt;

In php, I specified the same parameters for all cookies

session_set_cookie_params(60*60*24*14,'/','.portal.my');

I checked - all cookies are normally set on .portal.my and are available from any subdomains. But the problem arose in Ajax requests: The "Header set Access-Control-Allow-Origin "*"" parameter allows making Ajax requests to subdomains, but it ignores the cookies that come from them, although the firebug shows that they come. Tell me how to deal with this?
