To configure browser cache settings on Drupal 8, follow these steps:
1. Log in as an administrator on your Drupal site.
2. Go to Configuration > Development > Performance.
3. Scroll down to the Browser caching section.
4. Check the box next to “Aggregate and compress CSS files” and “Aggregate JavaScript files” to enable caching of these files.
5. Set the “Expiration of cached pages” and “Expiration of cached CSS/JS files” options to an appropriate value for your site.
6. Click on the “Clear all caches” button to apply the changes.
Note: Enabling browser caching can significantly speed up page load times for returning visitors, but it can also cause issues if your site frequently updates its content or files. Make sure to test your site thoroughly after making cache settings changes to ensure that everything is functioning as expected.
