What is HTTP? 

The Hypertext Transfer Protocol (HTTP) is designed to enable communications between clients 

and servers. 

HTTP works as a request-response protocol between a client and server. 

A web browser may be the client, and an application on a computer that hosts a web site may 

be the server. 

Example: A client (browser) submits an HTTP request to the server; then the server returns a 

response to the client. The response contains status information about the request and may also 

contain the requested content.
