Client cache TTL for default image responses. Provides the expiration interval for default image responses (responses which return a default image specified with either defaultImage= or attribute::DefaultImage).
Only applied when the default image is not associated with a catalog record or when the default image catalog record does not provide a specific catalog::Expiration
value.
Real number, 0 or greater. Number of hours until expiration since the reply data was generated. Set to 0 to always expire the reply image immediately, which effectively disables client caching for default image responses. Set to -1
to mark as never expire
.
Inherited from default::DefaultExpiration
if not defined or if empty.
TTL (Time-To-Live) is the duration before the cache expires. The default TTL is 1 hour.
