짬타이거 화이팅!

iframe페이지 내에서 쿠키 사용시 적용이 안되는경우 이는 P3P 규약에 의해 적용되지 않는것이다.

처리방법 : Iframe의 페이지 헤더에 아래 코드를 추가해준다.

-Asp.Net

HttpContext.Current.Response.AddHeader("p3p","CP=\"IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT\"");

-PHP

header('P3P:CP="IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"');

-JSP

response.addHeader("P3P","CP=\"IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT\"");
