Asp.net solves the problem of IFRAME cross-origin cookies read/write.

I used IFRAME when I was working on the project a few days ago.

On page A, I nested an IFRAME to display page B. However, I created a cookie on page B but cannot obtain it.

Later, I checked a lot of information and found a solution.

Add to Asp.netCode:

Response. addheader ("p3p", "cp = CaO PSA our ");

 

You can also add tags in HTML.

<Meta http-equiv = "p3p" content = 'cp = "idc dsp cor Cura ADMA our ind PHY onl com sta" '>

 

You can use p3p to read cross-origin cookies.

You can also configure the HTTP header on IIS
