Am I allowed to cache tiles in my backend server?

Question

I will be serving tiles via my backend server to the frontend of the webapp. Am I allowed to cache tiles to a) improve performance and b) avoid repeated lookups on the arcgis server if a user is panning around the same extent?

Hi @bearingwest ,

You cannot cache tiles on a server or service. You can check the Master Services agreement or the Product Specific agreement for the ArcGIS products you are licensing. The ArcGIS services are all hosted on CDN infrastructure and provide robust caching and performance, it shouldn't be necessary to add your own cache for performance and delivery.
