What is the difference between GET and POST data transfer methods from the user's interaction with the server?

The GET and POST data transfer methods differ in how the user interacts with the server and how data is transmitted:

• GET:

  • Data is transmitted in the URL as parameters (e.g., ?id=123&name=abc).
  • Used for retrieving data without changing the server state.
  • GET requests can be cached, stored in browser history, and shared via links.
  • Limited by URL length, so not suitable for large amounts of data.

• POST:

  • Data is transmitted in the body of the HTTP request, not visible in the URL.
  • Used for sending data to the server, such as creating or updating resources.
  • Not cached or stored in browser history.
  • Allows transmitting large amounts of data, including files.

From the user's perspective, GET requests are usually triggered by clicking links or refreshing the page, while POST is used when submitting forms or performing actions that change data on the server.
