REST

Full Title

Representational state transfer

Context

The core concept of the Web where the base HTTP message is:

• Stateless - any message can be sent to any End Point and must be processed.
• Asynchronous - HTTP was designed to react to user requests as the need is articulated by a user at his own time and place.

Problem

Nearly all interactions on the web occur in a burst where users expect that the service end point will remember the last transaction.

Solutions

Cookies and HTTP headers contain state data to be used from one message to the next.
