As a quick summary, the HTTP/1.1 protocol works as follows: The client (usually a browser) opens a connection to the server and sends a request. The server processes the request, generates a response, and closes the connection if it finds a Connection: Close header.

Similarly, how does a GET request work? Once the TCP connection is established, the client sends a HTTP GET request to the server to retrieve the webpage it should display. After the server has sent the response, it closes the TCP connection. GET requests are one kind of HTTP method a client can call.
