Questions tagged [http]

Hypertext Transfer Protocol (HTTP) is an application level network protocol that is used for the transfer of content on the World Wide Web.

Hypertext Transfer Protocol (HTTP) uses a client-request/server-response model. HTTP is a stateless protocol, which means it does not require the server to retain information or status about each user for the duration of multiple requests.
