22 | * Encodes the service name, typical output is "/page.svc" where "page" is a | |
23 | * service name. This is useful for the home and restart services, for example. | |
24 | * This encoder should be prioritized very low so that it doesn't prevent other | |
25 | * encoders from doing their work. | |
