1.12. How to enable caching
Caching is used to speed up data rendering and optimize the performance of web maps. It can be applied to vector and raster layer styles, as well as WMS and TMS layers.
To enable caching, you need:
Go to the “Tile Cache” tab in the corresponding resource
Activate the “Enabled” checkbox
In accordance with a specific task, set the settings for the maximum zoom level of caching, TTL, and if necessary, flush the cache and allow the use of cached tiles (tiles) when requesting pictures (image)
