All Implemented Interfaces:

ContainerRequestFilter

@Priority(value=1000)
public class CsrfProtectionFilter
extends Object
implements ContainerRequestFilter

Simple server-side request filter that implements CSRF protection as per the Guidelines for Implementation of REST by NSA (section IV.F) and section 4.3 of this paper. If you add it to the request filters of your application, it will check for X-Requested-By header in each request except for those that don't change state (GET, OPTIONS, HEAD). If the header is not found, it returns Response.Status.BAD_REQUEST response back to the client.
