I anticipate having to develop a front-end for an ArcGIS server, and until it's ready I've just been poking around the web interface of an existing instance to get a general understanding of where things are.
What other standard locations exist in a default ArcGIS setup, if no customization is done (or, equivalently, where I can find such information)?
I looked into the links posted by @Mapperz in the comments, and while they were informative about migrating to 10.2, they didn't talk much about conventions or defaults for the ArcGIS web interface. The second link mentioned the
arcgis/rest/services convention, but that was one of the ones I had already discovered.
