What is HTTP?

• Hyper Text Transfer Protocol
• Protocol to transfer of data from a web server to web browser – in many forms/format to communicate with each other over the Internet.
• Standard for transforming documents on World Wide Web (RFC 2616)

The result should be the same. It essentially means that the result of a successfully performed request is independent of the number of times it is executed. For example, in arithmetic, adding zero to a number is idempotent operation.
