I would like to setup a REST service through ArcGIS Server.
In this case I do not need a map service, but it seems like you can only deploy an SOE as an extension to another service. It seems weird to attach the SOE to a map service that it is not related to.
I would prefer to create the service as an SOE since it uses ArcObjects and so that it can be managed and deployed through the AGS management console.
I'm working with ArcGIS Server 10.1 on Windows with IIS.
