SNI

SNI, or Server Name Indication, is a technology used in secure internet connections. It allows a web server to present multiple SSL/TLS certificates on the same IP address and port number, enabling secure connections for different websites hosted on that server. When your browser connects, it sends the website's name to the server first, allowing the server to respond with the appropriate certificate. This is essential for enabling secure HTTPS connections for multiple sites, especially as it helps establish secure communications while optimizing server resources.
