Shared Cache Groups

Precautions

• Domain names in a shared cache group share the cached resources of the primary domain name. If no resources are cached, a large number of origin pull requests may be sent, occupying the origin server bandwidth. Exercise caution when adding a domain name to a shared cache group.
• A domain name can be added to a shared cache group only when Query Parameters is set to Ignore all or Retain all.
• Each shared cache group can contain up to 20 associated domain names.
• An account can have up to 500 shared cache groups.
• Before deleting a cache group, you need to remove associated domain names from the group.
