Caching

Caching accelerates the loading times of images as it allows to host them as close as possible to your end users. By caching, your ensure maximum performance of your website.

When this cache expires, the image will be requested from the origin and the new image delivered to the client.

Please note that these settings can be changed upon request via a ticket to our support team.

Browser cache expiration interval (Max-age): The time in seconds that the image is allowed to be re-used. For instance, max-age=86400 indicates that an image remains in the browser cache for the next 86400 seconds (24 hours).

CDN cache expiration interval (S-maxage): S-maxage = 31536000 indicates that the image remains in the CDN cache for 31536000 seconds (1 year)

Automatic origin image refresh: If you need to use a very small caching interval for a specific image (for example, snapshots from a live webcam or a specific chart with dynamically changing contents), you need to change the Automatic origin image refresh setting in your Admin console. This tells our resizing servers to update all origin images after this interval has expired.
