using the ResponseCachingMiddleware with VaryByQueryKeys

[ResponseCache(CacheProfileName = "DefaultCache", VaryByQueryKeys = new string[] { "id" })]

open chrome inspector
tick disable cache
go to page that uses a ResponseCache with VaryByQueryKeys

it throws:
InvalidOperationException: 'VaryByQueryKeys' requires the response cache middleware.

closing the inspector or untick disable cache work fine.

Using fiddler, adding Pragma: no-cache header is enough to make the site throw an exception.

Looks like incognito mode on safari render the actions with VaryByQueryKeys useless too.
