How does CloudFlare do it? (SSL related question)

vladka24

Hello, I'm seriously wondering how CloudFlare pulled it off... What am I talking about?
Well for example, my friend has this website: https://blazinhosting.net/ and if you look at the SSL Common Name it's directed to "ssl5609.cloudflare.com".

But the actual domain is blazinhosting.net.
So how can I pull this off also? I'm just very curious on how this works.

Very High tier cert.

CloudFlare can push additional domain names to their certificates automatically, they have a special contract with GlobalSign.

So, in theory, they can act as whatever domain they want

They can modify their cert anytime?

I actually don't see anything unique about this cert. It's a simple SAN + wildcard cert, but ssl5609.cloudflare.com is just listed as the first domain.

Yes, and this is how proxy works.
