localhostgate

Documentation

Overview

package localhostgate defines a feature gate that controls whether server-like receivers and extensions use localhost as the default host for their endpoints. This package is duplicated across core and contrib to avoid exposing the feature gate as part of the public API. To do this we define a `registerOrLoad` helper and try to register the gate in both modules. IMPORTANT NOTE: ANY CHANGES TO THIS PACKAGE MUST BE MIRRORED IN THE CONTRIB COUNTERPART.
