SPR-11792, many defaults regarding HTTP caching policies have been updated to the latest standards.
By default, RedirectViews have http10Compatible set to true, which means that they use HTTP 302 as a default HTTP response status. Setting this property to false make RedirectViews use HTTP 303 by default.
Now when set to false, RedirectViews don't use the RESPONSE_STATUS_ATTRIBUTE request attribute as a response HTTP if it is available. Both configuration choices should behave the same regarding to this request attribute.
