I'm trying to publish a map with arcGIS for server and I want to create a cashed map service. I'm using ArcGIS 10.2 and following the tutorial. When I get to the section Publishing the map service, step 11 says to click the Caching tab in the Service Editor. There is no Caching tab in my Service Editor. I'm not sure whether it is a licensing issue or an extension I need to turn on, but if anyone can help it would greatly be appreciated.
