HTTP - How does it work?
On each hyperlink click, the browser (client) initiates a connection with the server at the "machine" (e.g. using UNIX BSD connect call on the default port 80, or a custom user-defined port)
A request is sent to the server, formatted as a MIME-like message.
The server replies with another MIME-like message which is received by the browser and either formatted in the browser window or viewed with a helper application.
The connection is closed on both sides. (The exception to this is the "server push" connection.)
