From ArcExplorer, you can view a MapService. An ArcIMS Spatial Server can serve a Feature MapService or an Image MapService.
A Feature MapService uses the Spatial Server's feature streaming capabilities. The server bundles data and streams it to the requesting client. Requests are sent to a Spatial Server only when additional data is needed.
Image MapServices use the Spatial Server image rendering capabilities. When a request is received, a map is generated on the server, and the response is sent back as an image. A new map image is generated each time a client requests new information.
Entering a service name to a Spatial Server on the WWW Connection dialog box is optional. If you do not specify a service name, you will be connected to all the services.
