Accelerated Domains cache policies

Accelerated Domains implements cache policies in a smart way depending on the type of asset, and the cache TTL (time-to-live) is determined by the Cache Engine itself to enhance performance. The Cache Engine implements efficient caching headers used both by the Accelerated Domains Cache Engine itself, and browsers.

Like with all correctly configured cache the Accelerated Domains Cache Engine only caches GET requests.

Asset type	Browser cache	Edge cache
CSS	Up to a year	Up to a year
JavaScript	Up to a year	Up to a year
Images	Up to a year	Up to a year
HTML	10 minutes	Up to 24 hours
Other assets	Up to a year	Up to a year

What do to when you change an asset?

To make sure an asset it updated across all caches, both on the visitors device and Accelerated Domains, we recommend using version strings in the URL.
