urlMask

A template to parse function field from a request URL. URL mask allows for routing to multiple Cloud Functions without having to create multiple Network Endpoint Groups and backend services. For example, request URLs "mydomain.com/function1" and "mydomain.com/function2" can be backed by the same Serverless NEG with URL mask "/". The URL mask will parse them to { function = "function1" } and { function = "function2" } respectively.
