Hypertext Transfer Protocol (HTTP) is an application-layer protocol for transmitting hypermedia documents, such as HTML .
It was designed for communication between web browsers and web servers, but it can also be used for other purposes.
HTTP follows a classical client-server model, with a client opening a connection to make a request, then waiting until it receives a response.
HTTP is a stateless protocol, meaning that the server does not keep any data (state) between two requests.
