Hi, However, if client like OpenLayers or Leaflet is making 256x256 sized WMS requests they are always the same for the same tile and thus cacheable as well.

Dan, > 1. No, you are not correct. The browser CAN cache those requests. Hum, in wms mode? I am not sure. In WMTS, TMS, etc mode yes but not in WMS as the request will change each time. Y. 2018-05-30 19:15 GMT+02:00 Dan Little <theduckylit...@gmail.com<mailto:theduckylit...@gmail.com>>: Please take a moment to do a bit more reading about how browser caching works: - https://developers.google.com/web/fundamentals/performance/optimizing-content-efficiency/http-caching You cannot directly control what the browser chooses to cache but you can use mod_expiry and friendly-reusable URLs (like XYZ tiles) to help in that cause. Repetitive WMS requests will be caught by the cache but it's much harder to get a hit as it will change when the screen size, resolution, or small shifts in locations differ. To directly answer your questions: 1. No, you are not correct. The browser CAN cache those requests. 2. Yes, the browser will cache those images. Cheers.

I enabled mod_expires and noticed that the png files for the buttons are cached unfortunately the mapcache png files are not cached. I presume it might not be possible to cache images from mapcache when used in WMS mode, but it might be possible when using either WMTS, or TMS mode. Questions: 1. Am I correct that we cannot use browser or client caching with mapcache in wms mode? 2. Can we use browser cache when using WMTS or TMS services? I am using GeoMOOSE which should be able to consume xyz TMS tiles. Thanks!
