The first party extra domains use a different domain and .tld altogether.<p>A bit like how google.com is for maps and anything users upload go to googleusercontent.com.<p>LFGSS is served from www.lfgss.com and the user assets go via lfgss.microco.sm, and proxied user assets (another level of distrust altogether) are going via sslcache.se .<p>I own all of the domains, and they&#x27;re on the same CloudFlare acount, but we don&#x27;t yet offer ways to give users control over which domains get SNI&#x27;d together, and this is especially true when the domains are on different CloudFlare plans.<p>That said... it&#x27;s cool. To reduce everything from 8 domains down to 3 or 4 is a significant enough improvement that I&#x27;m happy.
