Edge and Browser Cache TTL

​​ Edge Cache TTL

Edge Cache TTL (Time to Live) specifies how long to cache a resource in the Cloudflare edge network. Edge Cache TTL is not visible in response headers and the minimum Edge Cache TTL depends on plan type.

• Free - 2 hours
• Pro - 1 hour
• Business - 1 second
• Enterprise - 1 second

​​ Browser Cache TTL

The Browser Cache TTL sets the expiration for resources cached in a visitor’s browser. By default, Cloudflare honors the cache expiration set in your Expires and Cache-Control headers but overrides those headers if:

• The value of the Cache-Control header from the origin web server is less than the Browser Cache TTL Cloudflare setting.
• The origin web server does not send a Cache-Control or an Expires header.

Unless specifically set in a page rule, Cloudflare does not override or insert Cache-Control headers if you set Browser Cache TTL to Respect Existing Headers.
