I have a multiple domains like site.com and web.site.com.
I have already login system, but if i login in site.com, web.site.com don't know the login, because I'm using session_start();.
So, is there a way to "choose" or something else to do to all my subdomains to know that user is loged in?
Like google and youtube....
I tried to do it like browser automatically post the user sp. ID but i't doesn't work for sub-domains if you go back.
Thanks.
