The most practical way of learning you can ever find (also made me laugh 2/3 times lol). I wish a lot of articles, blogs, even documentations where written the way you explain things. :)
Cheers.

Thank you for this informative video!
I have a question: On webservers and proxy servers there is the option to turn on SNI or off.
Is there any reason SNI should be set to false in stead of true when hosting multiple sites? It seems that when you host multiple sites the option should always be true?

I have 2 questions. 

1. The one which does SNI resolving can be any web server/proxy like Apache/Nginx/HAProxy ? If so any extra configuration is needed right?
2. During TLS, we use SNI to create a proper symmetric key between browser and server(a.com). Now browser encrypts the content (headers and body) and send it. For the normal subsequent GET request how come the proxy/web server will be able to decrypt the content and see the header to route it to a.com?

Hi, I have a question,
As to what you explained that if I go to an IP address directly I will not be able to get the page as the SNI will be the same as the IP address and the host won't know what to do with it, what will be if I use a header editor like modheader and add an sni of the domain name for that site, would that work?
