About

An http message is a textual message that consists of:

• a header section
• and an optional entity (ie body).

There are two kinds of messages:

• requests from client to server
• and responses from server to client

They differ in the format of the first line, but both can have header fields and an optional body (entity).

A request followed by a response is called a fetch.

Example

Example with a get request that shows only a list of header
