This article describes how to use the Time To Live (TTL) attribute and how it works.
When you create a container in Cloud Files and you make that container public, the files within that container have a designated TTL. The TTL is the time interval after which the CDN rereads the contents of the container. This attribute and its value can be modified in the CDN through the Cloud Files user interface.
New values take effect after the current TTL cycle is completed. The TTL can be any value between 15 minutes and 50 years. Use higher numbers for static content that doesn’t change often, and use smaller numbers for content that changes more often. If you require a longer TTL, use the Cloud Files Application Programming Interface (API) to set TTL.
Use the following steps to modify a container’s TTL within the Cloud Control Panel:
