Disable Caching Setting During Development

Disable the secure and persistent browser caching setting during development in a sandbox or Developer Edition org to see the effect of any code changes without needing to empty the cache.

The caching setting improves page reload performance by avoiding extra round trips to the server.

Disabling secure and persistent browser caching has a significant negative performance impact on Lightning Experience. Always enable the setting in production orgs.

Warning

From Setup, enter Session in the Quick Find box, and then select Session Settings.
Deselect the checkbox for “Enable secure and persistent browser caching to improve performance”.
Click Save.
