HTTP is Hyper Text Transfer Protocol which is Stateless protocol. Client means Browser sends requests to web server for web pages and images. After processing on request by server it sends back the response to client then connection between the client and server will disconnected.

HTTP Request contains the series of HTTP headers, header fields and message body. HTTP response contains a Status line, series of headers, a blank line and response body.


When end user sends request to server in the form of data, json and many more things than Server will process on that request and sends back to end user in the form of HTML. This single request and response called as Context.

Context = Request + Response
