I know browsers block cross domain cookies for security reasons. I’m wondering if there is a way around it? I have a WP website and also a url shortener, the URL shortener does some tracking by grabbing the WP username from the cookie, if it is set.
I’ve moved my url shortener to a new short domain and obviously the tracking system has stopped grabbing the username from the cookie. Is there any way I can reintroduce this functionality?
