Hello, i have 2 different Wordpress sites in the same domain (one in primary domain and another in a subdoman).
I noticed that in the first WP site that is placed in the root of the domain i see it’s only used the __cfduid cookie, in the WP site of the subdomain i see there are two other cookies: cf_ob_info and cf_use_ob.
What they are? They are strictly necessary?
Why they are used in the WP site of the subdomain and not in the other WP site of promary domain?
Thanks in advice.
