strange behaviour - logged in to http://www.mypage.com but not in to http://mypage.com

Question

I am logged in into my page without www. If I add www. it shows that i am not logged in.

 
What could be the reason ???

Here on q2a one i slogged in to both "urls" automattically.

 

EDIT:

I know I can redirect non-www to www, but here on q2a.org I see me logged in under both roots,

that is what I want to achieve

Answer 1

I think u must look in qa-config.php files. 

If you wish, you can define QA_COOKIE_DOMAIN so that any cookies created by Q2A are assigned

to a specific domain name, instead of the full domain name of the request by default. This is

useful if you're running multiple Q2A sites on subdomains with a shared user base. 

 

define('QA_COOKIE_DOMAIN', '.example.com'); // be sure to keep the leading period
