title: Cross Domain Cookies with IFrame in Internet Explorer
body: <p>I had a client's requirement for opening a another domain link in Iframe. This thing works fine with Firefox, Chrome but in Internet Explorer its giving error that cookies are not enabled. When I directly open that link it work fine with IE, but with IFrame its not the same case. I did some search on Google and didn't find a proper answer for it. I just want to confirm is there any coding fault from my side? I also found this solution for the problem</p>
  
  <p>In PHP: </p>
  
  <pre><code>header ( "p3p:CP=\"IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT\"");
  </code></pre>
  
  <p>But its not working on my case. I am not sure where should I put this, because I can change the code of my website if require. But I can't change the Iframe site, Since we are not the owner.</p>
  
  <p>This project is built in PHP.</p>
  
  <p>Any help would be much appreciated.
  Thanks in advance</p>
