Resource abuse is not good — cache responsibly. In the hugo configuration file (config.yaml, config.json, config.toml) set the cache expiry time. The default is 12h (12 hours) for remote fetches and -1 (forever) for assets, images, and modules. The time scales are seconds (s), minutes (m), and hours (h). Turn off a cache by setting a max age of 0.
