Post/Redirect/Get (PRG) is a web development design pattern that lets the page shown after a form submission be reloaded, shared, or bookmarked without ill effects, such as submitting the form another time.
POST is therefore suitable for requests which change the state each time they are performed, for example submitting a comment to a blog post or voting in an online poll. GET is defined to be nullipotent , with no side-effects, and idempotent operations have "no side effects on second or future requests".
The GET method requests that the target resource transfer a representation of its state. GET requests should only retrieve data and should have no other effect.
