Storage can bind multiple custom domains through the HTTP gateway
Cloud storage now supports binding multiple custom domains and serving files through the HTTP gateway.
You can bind domains directly on the "Storage - Domains" page in the console, or add an associated resource of type "Storage" in the HTTP gateway's route management. A single bucket can bind multiple custom domains, each with its own trigger path (such as / or /storage). All custom domains bound through these methods can be managed together in the HTTP gateway.
