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|
|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.
