title: safari does not allowed cross-domain cookies in iframe
body: <p>IE &amp; Safari Browser blocks cross-domain cookies in an iframe. </p>
  
  <p>e.g.
  I have two websites, let's say they're <code>example.com</code> and <code>anotherexample.net</code>. </p>
  
  <p>On <code>example.com</code>, I have one page <code>http://example.com/someform.asp</code> and in this page i am using cookies. When I open <code>http://example.com/someform.asp</code> directly in browser, it is working fine.  </p>
  
  <p>On <code>anotherexample.net</code>, I have page <code>http://anotherexample.net/page.asp</code>, this page contains an <code>IFRAME SRC="http://example.com/someform.asp"</code>. Now when we open <code>http://anotherexample.net/page.asp</code> page in browser, the cookies for <code>example.com</code> are not saved. In Firefox and chrome this problem doesn't appear.</p>
  
  <p>I found that using p3p policy we can fix this, but after setting below p3p policy in IIS response header and its works for IE only.</p>
  
  <pre><code>P3P : CP="This is  a P3P policy! See  http://www.workplaceanswers.com/privacy-and-terms/"
  </code></pre>
  
  <p>But, I am still getting the same error in safari. I have tried with different p3p policy values as below but not able to fix it.</p>
  
  <pre><code>P3P : CP="CUR ADM DEV HIS TEL STA STP COM”
  P3P:CP="IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT”
  P3P:CP="IDC DSP COR CURa ADMa OUR IND PHY ONL COM STA”
  </code></pre>
  
  <p>Is there any way to make this work in Safari?</p>
