Enable Secure Browser Caching

Enable secure data caching in the browser to improve page reload performance by avoiding extra round trips to the server.

This setting is selected by default.

Disabling secure and persistent browser caching has a significant negative performance impact on Lightning Experience. Only disable in the following scenarios:

  • Your company’s policy doesn’t allow browser caching, even if the data is encrypted.
  • During development in a sandbox or Developer Edition org to see the effect of any code changes without needing to empty the secure cache.

Warning

To disable secure date caching:

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