This was also wrong, have updated

Note has a different syntax to the HTTPCacheControlMiddleware example above as we set the Injector config here meaning there's no need to 'unset' the default values like we do above setting HTTPCacheControlMiddleware.defaultVary.X-Forwarded-Protocol: false -- HTTPCacheControlMiddleware lacks the getDefaultVary() and setDefaultVary() methods so we need to use that approach above
