Try creating a redirect function from non-www to www. See this topic: WWW to non-WWW Redirect with PHP

put this in your globals, or in your includes file, or just add it before any session_start() call.

ini_set("session.cookie_domain",".example.com");


another option would be to to add this:

php_value session.cookie_domain .example.com

to your .htaccess

  • @tamildinesh yes, the code above will do exactly what you want.. just try it. I've also added one more option for you – Adi May 02 '12 at 11:26

Your session is maintained by a cookie. When you log on to www.example.com, a cookie is saved for this domain by default, which is represented with every request to a URL in this domain. example.com is a different cookie domain, and the cookie won't therefore be presented.

Solutions are to either redirect from example.com to www.example.com as Andrei suggested, or to make the cookie domain match as Adnan suggests - both valid answers.

Try clearing browser cache deleting temporary files and prefetch files clear dns from cmd ipconfig/flushdns

re open browser login, writing or removing www should not alter with session since it runs on server.

make sure you are not Re - Starting session.
