Examples of org.springframework.security.web.savedrequest.SavedRequestAwareWrapper

org.springframework.security.web.savedrequest.SavedRequestAwareWrapper
Provides request parameters, headers and cookies from either an original request or a saved request.
Note that not all request parameters in the original request are emulated by this wrapper. Nevertheless, the important data from the original request is emulated and this should prove adequate for most purposes (in particular standard HTTP GET and POST operations).

Added into a request by {@link org.springframework.security.web.savedrequest.RequestCacheAwareFilter}. @author Andrey Grebnev @author Ben Alex @author Luke Taylor
