no, if you're make an ajax call that sets the cookies with HTTP (inside the iframe) Ie6 bypasses the security policy and sets the cookie. This is because if your compact p3p policy header is invalid, IE actually treats it as a good policy and accepts 3rd party cookies. This imposes a bunch of restrictions, like being just unable to access most properties of the window.parent object. Found a nice blog entry that explains the problem here: https://stackoverflow.com/questions/389456/cookie-blocked-not-saved-in-iframe-in-internet-explorer/16737097#16737097, https://stackoverflow.com/questions/389456/cookie-blocked-not-saved-in-iframe-in-internet-explorer/7921196#7921196, https://stackoverflow.com/questions/389456/cookie-blocked-not-saved-in-iframe-in-internet-explorer/3552272#3552272, https://stackoverflow.com/questions/389456/cookie-blocked-not-saved-in-iframe-in-internet-explorer/16053685#16053685, https://stackoverflow.com/questions/389456/cookie-blocked-not-saved-in-iframe-in-internet-explorer/20982934#20982934, https://stackoverflow.com/questions/389456/cookie-blocked-not-saved-in-iframe-in-internet-explorer/759845#759845. For a more detailed explanation see my answer here: Set P3P code in HTML, I got this from: http://dot-net-web-developer-bristol.blogspot.com/2012/04/setting-p3p-header-in-rails-session.html. After upgrading to Xcode 12. Index.php: Just send an additional header. Cookies don't block rendering of an iframe. If the page inside the IFRAME doesn't have a Privacy Policy, its cookies are blocked (which is indicated by the eye icon in status bar, when you click on it, it shows you a list of blocked URLs). In other words, third-party cookies are cookies that are set by a website other than the one you are currently on. Internet vs. 1. Predictably, that performance had the potential to introduce security vulnerabilities such as Cross-Site Request Forgery (CSRF) attacks. From what I can tell Safari is using ITP and is blocking third party cookies. We will be starting with allow-scripts. Sharing cross-site cookies is not always an issue; however, it has the potential for abuse. It has been blocked, as Chrome now only delivers cookies with cross-site requests if they are set with SameSite=None and Secure. Thanks! This is a nice idea, and luckily most of the time not providing this header won't cause any issues (read browser warnings).

Then add this p3p module, and enable this module at middleware.

Enable session cookies for iframe in page in WkWebView / mobile , I just had a similar issue.

I have more on this in a post here: http://posheika.net/?p=110. That IFRAME displays a form for the user to fill out and submit to http://example.com/process.asp. One solution that I haven't seen mentioned here, is using session storage instead of cookies. But in this case, the cookies were still blocked. Mozilla is not blocking cookies. You can show the page in a popup window which sets the necessary cookies (like authentication, etc) and then access these cookies from within the iFrame. To review: in order for IE to accept 3rd party cookies, you need serve your files with an http header called p3p in the format: BUT, p3p is pretty much dead as a standard at this point and you can easily get IE to work without investing the time and legal resources in creating a real p3p policy. example.com uses cookie-based sessions (and there's nothing I can do about that), so without cookies, process.asp won't execute. In Chrome 80, which will be released to early release channels in January 2020, Chrome will block mixed audio and video resources—technically, it will try to load them over a secure HTTPS connection instead and block them if … This is done to improve overall web security and eliminate certain classes of CSRF attacks. If this header doesn't have have any legal ramifications this header should be ignored (or alternatively, generate a warning or notification in the console). So you have one additional reload for the browsers you configure. The article quotes a (now broken) link to a Microsoft kb article.
