Q: What is the difference between GET and POST requests?

A: The key differences are:

  1. Purpose: GET is used to request data from a specified resource and should not change the state of the server. POST is used to submit data to be processed to a specified resource and can change the server state.
  2. Data Transmission: GET requests send data in the URL (query string), which is visible in the browser's address bar. POST requests send data in the request body, which is not directly visible.
  3. Length Limitation: GET requests have a limit on the length of the URL. POST requests have no inherent limit on the size of the data that can be sent.
  4. Security: Data sent via GET is less secure as it is transmitted in plain text. POST is more suitable for sensitive data, as it is sent in the request body. GET is safe for retrieving data, while POST is intended for submitting data that changes the server's state.
