This is a common design error in many web applications.

If there is a public cacheable object on an URL then there must not be
personalized or protected variants on the same URL. Exception is if the
conditions for when a personalized/protected variant is returned can be
expressed via the Vary header.

The Authorization restriction only goes the other way, making sure that
the cache won't cache content requiring Authorization as if it was public
content not requiring Authorization.
