The Browser Cache Expiration specifies how long Cloudflare-cached resources will remain on your visitors' computers. Cloudflare will honor any larger times specified by your server. A high value ensures faster load times for repeat visitors. However, a high value also means slower update times when those resources are modified. If you are unsure, four hours is a safe setting.
You can get to the Browser Cache Expiration settings by going to the "Caching" tab and set the time with the drop down menu.
To get to this page:
- Login to your Cloudflare account.
- From the dropdown menu, select the domain.
- Select the Caching tab.
