How to share resources among multiple maps

[WebHero0544]

Hello, how to instantiate multiple maps and achieve synchronized map interaction while only requesting one resource to be shared by all maps?

Short answer: Resources are cached by the browser, but each map instance has its own tile cache.

For a longer answer:
Can you elaborate what exactly you want to achieve, what the problem is and what you have tried so far?

For example, I instantiate 12 maps and use the same style. When operating on the current map, the status will be synchronized to the other maps. At this point, it is desired that the resources in the style be requested only once. This way, the instantiation of the maps will be faster and there will be no delay in the requests for other data.
