HTTP

Q 1) Why HTTP is called stateless protocol ?
answer:

•           HTTP is stateless protocol which means that a different connection between a client and server is established for each request.
• HTTP is stateless protocol because each command request is executed independently without any knowledge of the request that were executive before it.
• A stateless protocol doesnot require that server to retain information or status about each user for duration of multiple request.
• This simplifies the contract between client and server and in many cases minimizes the amount of data that needs to be transfered.
