HTTP

HTTP headers let the client and the server pass additional information with an HTTP request or response.

HTTP headers are the code that transfers data between a Web server and a client. HTTP headers are mainly intended for communication between the server and client in both directions.

In 1989, while working at CERN, Tim Berners-Lee wrote a proposal to build a hypertext system built over the existing TCP and IP protocols over the internet.

The evolution of HTTP has led to the creation of many applications and has driven the adoption of the protocol. The environment in which HTTP is used today is quite different from that of the early 1990s.

Master Talia synced Red’s cyberware with the amplifier and when she saw that the data stream has started told Red : Never let yourself near the darkness when you are in there, alright? This was the risk I was telling you about earlier. If you let the voices cover you in the darkness you might not wake.” replied Master Talia. “Don’t worry Master Talia, I will be careful” said Red and closed her eyes. Are you ready? I am amplifying the resonance in three, two, one.” replied Master Talia. But as soon as the resonance amplified Red couldn’t even hear the countdown and found herself in a dark , dream-like world. - Journals of Order of Epoch, 2341 Anno Domini

HTTP headers let the client and the server pass additional information with an HTTP request or response. An HTTP header consists of its case-insensitive name followed by a colon (:), then by its value.

Request headers

A request header is an HTTP header that can be used in an HTTP request to provide information about the request context so that the server can tailor the response.

Response headers

Holds additional information about the response, like its location or about the server providing it.

It was pitch black, and Red felt alone, cold inside darkness. She tried to control her breath and focus on the white noise that she can hear in the background. And as she focused more that noise amplified and started to illuminate the darkness. She caught her breath and calmed herself down. She called out “brother?”. Her voice also created a new shape in the air, a new energy flow that illuminated its own light. But this light was different than the rest of the shapes as it was brighter than the rest. And just as this new shape appeared as a manifestation of Red’s voice in the darkness, all the other voices stopped just as a sentient being realized something and become alerted. - Journals of Order of Epoch, 2341 Anno Domini

Representation headers

Contains information about the body of the resource, like its MIME type, or encoding/compression applied.

Payload headers

A payload header contains representation-independent information about payload data, including content length and the encoding used for transport.
