What parts does an HTTP request consist of?

An HTTP request consists of several main parts:

1. Request Line — contains the method (GET, POST, etc.), URL (resource path), and HTTP protocol version.

2. Headers — a set of key-value pairs that convey metadata about the request, such as content type, cookies, authorization.

3. Blank line — separates headers from the body of the request.

4. Body — an optional part that contains data sent to the server (for example, in POST requests).

Example of a request line:

POST /api/user HTTP/1.1

In Go, when working with the net/http package, these parts are accessible through the http.Request structure.
