  <p>If i understand correctly, it is not possible to save cookies for different domains: only sub domains of the same root.</p>
  
  <p>However, when looking on some sites, i see this happening.</p>
  
  <p>The most obvious example is on youtube where there are cookies for youtube.com and google.com present.</p>
  
  <p>How is this possible?  How are they achieving this?</p>
