The HTTP route for a service is the publicly-accessible directory path that maps to the root of your service. For example, if you set the HTTP route for a service to be
/myservice1, and your app is serving on the domain
mydomain1.com, then requests for
mydomain1.com/myservice1 will be routed to this service for a response. This allows you to use different services that are exposed at different subdirectories, each with their own configuration, capacity, and scaling characteristics.
