Question

Which request is better, GET or POST?

Answer 1

In AJAX HTTP GET request is more reliable as the data does not change for a given URL requested. HTTP POST should be used when state is updated on the server.

Answer 2

AJAX requests should use an HTTP GET request where the data does not change for a given URL requested.

An HTTP POST should be used when state is updated on the server. This is highly recommended for a consistent web application architecture.
