class ActiveStorage::Blobs::ProxyController

Parent:: ActiveStorage::BaseController

Proxy files through application. This avoids having a redirect and makes files easier to cache.

WARNING: All Active Storage controllers are publicly accessible by default. The generated URLs are hard to guess, but permanent by design. If your files require a higher level of protection consider implementing Authenticated Controllers.
