The WMTS tiles requests made in the RESTful way don’t use the GWC tiles cache. This works fine with KVP requests

We have a GeoServer 2.18.2 instance, with several layer groups.
A lot of WMTS tiles are in the GWC cache for this layer (… I mean this LayerGroup).

Requests are super fast when done in KVP, because the tile is fetched from cache :
https://MyServer/geoserver/MyWorkspace/gwc/service/wmts?layer=MyLayer&style=&tilematrixset=Tiles_31370&Service=WMTS&Request=GetTile&Version=1.0.0&Format=image%2Fpng&TileMatrix=Tiles_31370%3A9&TileCol=262&TileRow=173

But requests made in REST are very slow, because cache is not used and a lot of GetMap are made (for each layer of the layergroup)
https://MyServer/geoserver/MyWorkspace/gwc/service/wmts/rest/MyLayer/Tiles_31370/Tiles_31370:9/173/262?format=image/png

It’s strange that the two “URL flavours” (KVP / REST) have a completly different behavior…

It’s also strange that in the WMTS capabilities, the “GetTile” operation list only “KVP” as allowed values but the “RessourceUrl” element for the layer shows a template based on the REST syntax
