Good afternoon!

Today I was working with my slimtimer session like daily. Then i closed session and the url showed "http://slimtimer.com/?check_cookie=false". My curiosity said me : "delete of the url ?chek_cookie=flase" and when i press enter key my session was opened again...
Again, I closed session and return my curiosity...

Whenever I delete this part of the url (?chek_cookie=flase) it happens that after the session itself starts.

Greeting!
