That is, calling the same PUT request multiple times will always produce the same result.

In contrast, calling a POST request repeatedly have side effects of creating the same resource multiple times.

The big difference is that a POST request is supposed to let the server decide how to (and if at all) create a new resource.

Historically (from the now obsolete RFC2616 it was to create a new resource as a subordinate (child) of the URI where the request was sent to).

The difference between PUT and POST is that PUT is idempotent: calling it once or several times successively has the same effect (that is no side effect), where successive identical POST may have additional effects, like passing an order several times.

The application saves request parameters and results so that you can share them.

When we send a POST request we generally intend to have some modification at the server such as updation, deletion or addition.

One of the classic example of a POST request is the Login page.
