What is the difference between GET and POST?

GET and POST are two main HTTP methods used for client-server interaction.

• GET is used to request data from the server. Parameters are passed in the URL (query string), and the request should not change the server's state. GET requests are cached and can be stored in the browser cache.

• POST is used to send data to the server, for example, when creating or updating resources. Data is sent in the request body, allowing for larger amounts of information and more secure transmission of confidential data. POST requests are not cached.

Example:

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

POST /users HTTP/1.1
Host: example.com
Content-Type: application/json

{"name": "Иван", "age": 30}
