I am using MaxCDN for my website, and to prevent hotlinking, I only allow my website's pictures to be displayed on whitelisted HTTP referrers, through MaxCDN's security settings.However, even though I have added every kind of Google domain I could find, my post's pictures won't show up in new Google+ Posts.These are the domains I have whitelisted so far:*.googleusercontent.com*.google.com*.googleapis.com*.gstatic.com*.googlegroups.com*.ggpht.comWhich server am I missing?
Which domain do I need to whitelist as an HTTP referrer for Google+?
google plus
