Kuidas server eristab sama kasutaja korduvaid päringuid?

Server distinguishes repeated requests from the same user using various identification mechanisms, for example:

• Cookies: on the first request, the server sends a cookie with a unique identifier to the client, which the client sends in subsequent requests.
• Sessions: the server maintains the user's state by associating it with a unique session identifier, usually transmitted via cookie.
• Authentication tokens (e.g., JWT): the client sends a token with each request, which the server verifies and uses to identify the user.

This way, the server can track and differentiate users, providing personalized and secure access.
