Answer 1

GET and POST are HTTP methods which can achieve similar goals

GET is basically for just getting (retrieving) data, A GET should not have a body, so aside from cookies, the only place to pass info is in the URL and URLs are limited in length , GET is less secure compared to POST because data sent is part of the URL

Never use GET when sending passwords, credit card or other sensitive information!, Data is visible to everyone in the URL, Can be cached data . GET is harmless when we are reloading or calling back button, it will be book marked, parameters remain in browser history, only ASCII characters allowed.

POST may involve anything, like storing or updating data, or ordering a product, or sending e-mail. POST method has a body.

POST method is secured for passing sensitive and confidential information to server it will not visible in query parameters in URL and parameters are not saved in browser history. There are no restrictions on data length. When we are reloading the browser should alert the user that the data are about to be re-submitted. POST method cannot be bookmarked
