An HTTP request line consists of three fields.

Correct Order for HTTP Request Line:

1. Request Method (e.g., GET, POST)

2. URI (Uniform Resource Identifier) (e.g., /index.html)

3. Protocol Version (e.g., HTTP/1.1)

Request Method

URI

Protocol Version

Comprehensive and Detailed Explanation:

Structure of an HTTP Request Message

An HTTP request message consists of:

1️⃣Request Line → Specifies the request method, the target resource (URI), andthe HTTP version.

2️⃣Headers → Provides additional request details (e.g., Host, User-Agent).

3️⃣Body (optional) → Used in methods like POST for sending data.

Format of an HTTP Request Line:

GET /index.html HTTP/1.1

GET → Request method

/index.html → URI (resource being requested)

HTTP/1.1 → Protocol version

Why Other Fields Are Incorrect?

❌Status Code → This belongs to an HTTP response, not a request.

❌Mixing Headers into the Request Line → Headers should be placed separately after the request line.
