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. |
