This instructs caches not to cache the response, as it may contain information specific to a logged in user. This is handled in most cases, but some forms of access such as the Python `in` operator were overlooked.\n\nThe severity depends on the application's use of the session, and the cache's behavior regarding cookies. The risk depends on all these conditions being met.\n\n1. The application must be hosted behind a caching proxy that does not ignore responses with cookies.\n2. The application does not set a `Cache-Control` header to indicate that a page is private or should not be cached.\n3.
