I own domain a.com, b.com, c.com. They are part of the same network. With safari 11, and more privacy oriented browsers, when someone has a cookie on a.com, it doesn't transfer over when they visit b.com unless they explicitly sign-on again. Is there any way to keep cookies persistent, across the three domains?

    *"With safari 11, and more privacy oriented browsers, it doesn't transfer over when they visit b.com"* -- it is not because of the privacy orientation of the modern browsers. This is how the cookies were designed when they were introduced (by the Netscape browser) back in the 90s. – axiac Nov 12 '17 at 15:27
