In what case and why is the GET HTTP method used when interacting with a server?

The HTTP GET method is used to request data from a server without changing the state of the resource. It is used when you need to retrieve information, such as loading a webpage, fetching data from an API, or downloading a file.

Features of the GET method:

• GET requests should not modify data on the server (they are idempotent).
• Request parameters are passed in the URL (in the query string).
• Usually used for retrieving data that can be cached.

Example: when loading a webpage, the browser sends a GET request to the server to obtain the HTML code of the page.
