Explain the differences between HTTP GET and POST methods when sending data to a server

Main differences between HTTP methods GET and POST:

• GET:

  • Used to request data from the server.
  • Parameters are passed in the URL (query string).
  • URL length limitation (depends on browser and server).
  • GET requests can be cached and stored in browser history.
  • Not recommended for transmitting confidential data.

• POST:

  • Used to send data to the server (e.g., forms).
  • Data is sent in the request body, not in the URL.
  • No restrictions on the size of transmitted data.
  • POST requests are not cached and not stored in browser history.
  • Suitable for transmitting large volumes of data and confidential information.

Example: when submitting a registration form, it is better to use POST, and to get a search results page — GET.
