But when the cache is added through APIs, we need not to specify the URL. Isn't it?
Only cache cache-path, cache-id and cache-policy are suffice to be inputted.
I have done that way without any issue. But Is it necessary to specify URL in .earth file?
Actually, I did building cache by program (not by .earth file).
Yeah, when URL is given, it happens.
But in my case i have built cache of larger area(country level). Once cache is built, source data will be moved to some other storage area. Cache will be used as read-only to display (which must be the purpose of "cache-only" as well).
