What is HTTP (hypertext transfer protocol)?
HTTP, or hypertext transfer protocol, governs how messages are formatted and transmitted on the internet and determines what actions servers and browsers should take based on commands.
An example is when a URL is input in the browser, an HTTP command is sent to the server and fetches the requested web page. HTTP is the primary protocol used for information transmission on the internet.
HTTP activity often influences web application performance, particularly the headers used by the client and server.
