protocol and usually runs over TCP. It specifies what messages the client may send to the server
and what responses the client receives. Request and response messages include headers in ASCII, and
the message content often uses a MIME-like format. The HTTP server allows a client (usually a
browser) to request web content such as web pages, images, and documents through HTTP and transfer
the content to the client.");
