Note: This release is in preview. Features described here don’t become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.

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 these scenarios.

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

Warning

Secure and persistent data caching isn't available for Salesforce mobile app.

To disable secure data 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.
