Can you explain what an HTTP GET request is and what its main purpose is?

An HTTP GET request is one of the methods of the HTTP protocol used to request data from a server.

The main purpose of a GET request is to retrieve a representation of a resource (such as a web page, image, or API data) without changing the server's state.

Features of a GET request:

• Parameters are passed in the URL (in the query string).
• The request should be idempotent, meaning repeated requests should not modify data.
• It is typically used to retrieve information rather than modify it.

Example of a GET request:

GET /users?id=123 HTTP/1.1
Host: example.com

This request fetches data for the user with id=123.
