title: Allow PHP sessions to carry over to subdomains
body: <p>I use PHP sessions (not cookies, except for session id cookie) for all user data, and when a user goes to their profile <code>user.mydomain.example</code> they are immediately &quot;logged out&quot; until then remove the subdomain.</p>
  <p>Is there a way to accept sessions from all domains as long as its <code>*.mydomain.example</code></p>
