This section explains how to set up the Cache Control Header Override (CCHO).
A Cache Control Header Override setting consists of the following:
- An internal Cache Control policy specified as TTL defaulting to seconds or optionally followed by one of the following letters to indicate units:
Alternately, the internal policy can be set to "as-is", "no-cache", or "no-store".
- An external Cache Control policy, following the same rules as the internal policy.
- A force attribute with possible values "yes" and "no". (This is an optional value for the external Cache Control policy only.)
