title: Cross-domain cookies in iframe Safari
body: <p>I have a problem with setting cookies in an iframe (which loads a site from another domain).<br>
  On my site X.COM I load <code>&lt;iframe src='Y.COM'&gt;</code>  </p>
  
  <p>Y.COM tries to set cookies, but Safari blocks they, as this site was not visited before. So loading Y.COM fails because it can't work without cookies. Is there a way to solve this issue?</p>
  
  <p>P.S. I cann't modify any data at Y.COM. </p>
  
  <p>P.S.S. Also we can modify Safari's settings - <code>"Accept cookies" = "Always"</code>, but it is not a solution for me - it seems to be impossible to lead every user to do it.. </p>
