Is it possible to prevent the sending cook to the domain from the address bar?
I was thinking... That has a user account in Google, Yandex, FB, VK, Mail.ru and the like the companies need to emphasize. Of course, 95% of the time he is logged in permanently, because inconvenient to enter the password.
And here comes the user to a completely left the website where they can stand - Google Analytics, Yandex direct, licalsi, widgets, comments, and so on. That is, search engines and social networks not just to track visits to other sites, but watch out by name.
Question: are there any technologies, settings, or extensions that would block sending cook to the server, if the document is loaded Ajax or iframe? Well, that is if the user comes specifically gmail.com and this url in the address bar - cookies should be sent. And if the site is completely different, but Google was there as a left-side loaded - it should not get any cookies for it, the browser should look like he just installed.
About AdBlock, uBlock, Ghostery, and other blockers of the scripts - it's all clear, it is also necessary, but it is another line of defense. It is about sending cook.
