According to the Http specification, any Http GET request should be idempotent and safe. In this context, these principles have the following meaning:
Idempotence: One or more calls with identical requests should return the same resource representation (As long as the resource has not changed on the server between calls).
Safety: The only action produced by a GET request is to retrieve a resource representation, no side-effects should be evident on the service side after executing the request....
