What components form an HTTP request and how do they interact?

An HTTP request is formed from several main components:

• Method (GET, POST, PUT, etc.) — determines the action the client wants to perform.
• URL — the address of the resource being requested.
• Headers — request metadata, such as content type, authorization.
• Body — data sent to the server (for example, in POST requests).

The interaction occurs as follows: the client constructs a request with the specified components and sends it to the server. The server receives the request, analyzes the method, URL, and headers, processes the body (if present), and returns a response. In Node.js, IncomingMessage objects (request) and ServerResponse objects (response) are used to read request components and formulate responses.
