An HTTP Request is a message sent by a client, such as a web browser, to a server to request information or resources. This request typically includes a method, like GET or POST, which indicates the type of action the client wants to perform. It also contains the URL of the resource and may include headers that provide additional information, such as the type of data the client can accept. When the server receives the HTTP Request, it processes the request and sends back an HTTP Response. This response contains a status code indicating whether the request was successful, along with the requested data or an error message if something went wrong.
