Class RequestForwarder

java.lang.Object
  org.bbqjs.spring.ajax.RequestForwarder

All Implemented Interfaces:

org.springframework.beans.factory.InitializingBean

Direct Known Subclasses:

ServerWhitelistRequestForwarder, SingleServerRequestForwarder

@Controller
public class RequestForwarder
extends Object
implements org.springframework.beans.factory.InitializingBean

Forwards requests on to remote servers. This controller is intended to work around the Single Origin Policy enforced by most web browsers. The Single Origin Policy dictates that an AJAX request can only be sent to the domain from which the JavaScript sending the request was loaded. This is to prevent cross site scripting attacks. Sometimes though that functionality is useful though (when writing a client for a remote API based service, for example). By default this class forwards to whatever the client requests. To limit the destination servers, use SingleServerRequestForwarder or ServerWhitelistRequestForwarder
