HTTP headers components

BASIC INFORMATION:

HTTP headers let the client and the server pass additional information with a message in a request or response. ^[1]

NOTE: Remember that Header::send() just like PHP's native header() must be called before any actual output is sent. It is a very common error to have spaces or empty lines that are output before headers are called. ^[2]

HTTP header

An HTTP cookie is a small block of data created by a web server while a user is browsing a website and placed on the user's device by the user's web browser. ^[3]

Cookies serve useful and sometimes essential functions on the web. They enable web servers to store stateful information on the user's device. ^[3]
