title: Session Transfer
body: <p>Have a question on sessions, heres the scenario I am facing,</p>
  <p>User hits site scraper.com and makes a request, this triggers web server of scraper.com to initiate a session on &quot;parent.com&quot;, the web server makes multiple
  POSTs and GETs to parent.com and arrives at a checkout page. Now the web server of scraper.com wants the user's browser to load the checkout page of &quot;parent.com&quot;, the same checkout page which <strong>scraper</strong>
  reached through the session it initiated. In order to do this the user's browser should hit parent.com with the same session id as the one that <strong>scraper</strong>'s web
  server has, this I think can't be done as cross domain cookies are not allowed.</p>
  <p>This is very similar to doing a search on kayak.com and when the user selects a flight from Delta Airlines the checkout page of delta.com loads.</p>
  <p>How can this be implemented? Is it possible to implement this with the co-operation of parent.com or in above example delta.com?</p>
  <p>If <strong>scraper</strong> and parent are having an agreement what exactly should parent support for the <strong>scraper</strong> domain to make requests like above possible?</p>
  <p>I hope I did not complicate the description, please let me know. Any responses would be very much appreciated.</p>
  <p>Cheers</p>
