Could you explain what is meant by an HTTP request in the context of web communications?

An HTTP request is a message sent by a client (e.g., a browser) to a server to request resources or perform actions on the web.

It consists of:

• Method (GET, POST, PUT, DELETE, etc.), which determines the type of operation.
• URL — the address of the resource.
• Headers — additional information (e.g., content type, authorization).
• Request body (optional), where data is transmitted (e.g., in POST requests).

Example: when you enter a website address and press Enter, the browser forms an HTTP GET request to the server to retrieve the page.

The server processes the request and returns an HTTP response with the required data.
