Solve : Why isn't the php session working on the subdomains??

1.	Solve : Why isn't the php session working on the subdomains??
Answer» Hi. I am making a website builder, and for some REASON, when I make a session on site.com, then the session doesn't work on builder.site.com. The CODE I am using in front of every page is: Code: [Select]session_set_cookie_params(1440, "/", ".red-host.org", false, false); session_start(); HEADER("Cache-Control: no-cache, must-revalidate"); header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); And the code that MAKES the session is: Code: [Select] session_set_cookie_params(1440, "/", ".red-host.org", false, false); session_start(); $_SESSION[$_SESSION_NAME]="$_POST[username]"; Any advice or help would be appreciated. Thanks.It's because the session_start() function uses a COOKIE for authentication, and the cookie is only stored for the builder.site.com path.Oh, so how can I fix this issue?
