Dexecure plays very well with your existing caching logic. We use the cache-control and exprires response header to decide how long to cache each resource. For example, if your server sets a cache-control header like max-age=3000, Dexecure caches the optimized resource for 3000 seconds.
As an intervention, Dexecure caches assets for 7 days if there is no cache-control header sent by the origin server. You can configure this default cache control time on your dashboard.
