What does an HTTP request look like?

An HTTP request consists of the following parts:

1. Request Line: Defines the request type, resource path, and protocol version.
2. Headers: Additional information about the request, client, or request body.
3. Blank line: Separates headers and request body.
4. Request Body (optional): Contains data sent to the server (e.g., in POST requests).

Example of a GET request:

// Request line: method, path, protocol version
// GET /index.html HTTP/1.1

// Headers: information about the client, request, etc.
// Host: www.example.com
// User-Agent: Mozilla/5.0
// Accept: text/html

// Blank line: separates headers from body (none in this case)

// Request body (empty for GET)

Example of a POST request:

// Request line
// POST /submit HTTP/1.1

// Headers
// Host: www.example.com
// Content-Type: application/x-www-form-urlencoded
// Content-Length: 25

// Blank line

// Request body
// name=test&value=data
