Hi JvD, The difference between the two is: the former doesn’t serve the content under the paths other than “/vod/” and “/live/”.
For example, for the request “http://traffic-server.sports.ipcdn.com/path/file”, the former doesn’t serve it while the latter does serve it. Regarding the use case, this is useful if: Under the same domain name, the contents under some paths are set by one configuration and the contents under some other paths are set by another configuration. For example, Different “Regex remap expression” can be configured for “http://traffic-server.sports.ipcdn.com/vod/” and “http://traffic-server.sports.ipcdn.com/live/”. Different traffic caches can be assigned for “http://traffic-server.sports.ipcdn.com/vod/” and “http://traffic-server.sports.ipcdn.com/live/”. Some different configuration items become possible because separated delivery services.

The Google doc example has map http://traffic-server.sports.ipcdn.com/vod/ http://origin.server.com/vod/ map http://traffic-server.sports.ipcdn.com/live/ http://origin.server.com/live/ But, isn't that the same as map http://traffic-server.sports.ipcdn.com/ http://origin.server.com/ ? If you want to send the /live to RAM and the /vod to disk, they can't be in the same deliveryservice table entry, since all those type if things are set there? Can you elaborate on the use case you are trying to solve?

In some cases, different delivery services with same domain name and different path prefixes are needed.
