Classes related to the caching of an HttpServletRequest which requires authentication. While the user is logging in, the request is cached (using the RequestCache implementation) by the ExceptionTranslationFilter. Once the user has been authenticated, the original request is restored following a redirect to a matching URL, and the RequestCache is queried to obtain the original (matching) request.


RequestCache Implements "saved request" logic, allowing a single request to be retrieved and restarted after redirecting to an authentication mechanism. 
SavedRequest Encapsulates the functionality required of a cached request for both an authentication mechanism (typically form-based login) to redirect to the original URL and for a RequestCache to build a wrapped request, reproducing the original request data.
