!!! Overview [1] [2]
[{$pagename}] ([HTTP]) is a [stateless] [request|HTTP Request]/[response|HTTP Response] [protocol] that operates by exchanging [messages] across a reliable transport [Application Layer] for transmitting [hypermedia] documents, such as [HTML]
[{$pagename}] [Standards] are generally defined within the [HTML Living Standard] [Specification]
[{$pagename}], though often based on a [TCP]/[IP] [Protocol Stack], it can be used on any [Reliable protocol] transport layer.
[{$pagename}] follows a classical [Client-server] model, with a [client] initiating a connection to make a [request|HTTP Request], then waiting until it receives a [response|HTTP Response].
[{$pagename}] is a [stateless] [protocol], meaning that the server does not keep any [data] ([state]) between two requests.
A [{$pagename}] "[client]" ([user-agent] or [Browser]) is a [application] that establishes a connection to a [server] for the purpose of sending one or more [HTTP]/[HTTPS] requests.
An [{$pagename}] "[server]" is a [application] that accepts connections in order to service [HTTP Request] by sending [HTTP Response].
The terms "[client]" and "[server]" refer only to the roles that these programs perform for a particular connection. The same program might act as a [client] on some connections and a [server] on others.
The term "[user-agent]" refers to any of the various client [application] that initiate a request, including (but not limited to) [browsers], spiders (web-based robots), [command-line] tools, custom [applications], and [mobile Device] [apps].
The term "origin server" refers to the program that can originate authoritative responses for a given target [resource].
The terms "sender" and "recipient" refer to any implementation that sends or receives a given [message], respectively.
[{$pagename}] relies upon the [Uniform Resource Identifier] ([URI]) standard [RFC 3986] to indicate the target resource and relationships between [resources].
[Messages] are passed in a format similar to that used by [Internet Mail|email] [RFC 5322] and the [Multipurpose Internet Mail Extensions] ([MIME]) [RFC 2045] (see Appendix A of [RFC 7231] for the differences between [HTTP] and [MIME] messages).
