Certainly a dummy question but I can't find where it is possible to define the 'tile servers' property of a tiled MapService.
For example, on the REST API of the following service, we can read the property 'Tile servers' :
I thought it was because it is an ArcGIS Server 10.4 and I am using 10.3.1 but according to the documentation it appeared at 10.1
I did not find it neither at the publication of a cached service nor somewhere on the ArcGIS Server manager, so where is it ? What did I miss ?
Many thanks for your help,
