HTTP Keep-Alive - In Light
HTTP Keep-Alive is a feature of web servers that allows clients to keep connections open. It's also called "persistent connections." The idea behind HTTP Keep-Alive is to prevent the connection from timing out and closing, which would require the client to reconnect. This saves time for both users and the website’s server. HTTP/1.1 is designed to allow keep-alive connections by default, but HTTP/1.0 is not.
