View Source ActivityPub.Safety.Containment (bonfire_umbrella v0.9.10-cooperation-beta.62)

This module contains some useful functions for containing objects to specific origins and determining those origins. They previously lived in the ActivityPub Transformer module.

Object containment is an important step in validating remote objects to prevent spoofing, therefore removal of object containment functions is NOT recommended.
