title: Why is PHP saving each session in multiple directories?
body: <p>I noticed PHP saves each session on my domain in multiple directories.
  I noticed this when i checked the "path" under each cookie in my domain.
  It saves the user's email session for instance in my "ajax", "pages", "subpages", "root" path.
  This is unfortunately bloating the number of cookies on my domain since i extended each session with cookies so as to extend their lifespan. 
  Is it right to limit this directory to one? And if yes, how do i go about it?</p>
