clientTtl property
Specifies a separate client (e.g. browser client) maximum TTL for cached content.
This is used to clamp the max-age (or Expires) value sent to the
client. With FORCE_CACHE_ALL, the lesser of clientTtl and defaultTtl
is used for the response max-age directive, along with a "public"
directive. For cacheable content in CACHE_ALL_STATIC mode, clientTtl
clamps the max-age from the origin (if specified), or else sets the
response max-age directive to the lesser of the clientTtl and
defaultTtl, and also ensures a "public" cache-control directive is
present. The maximum allowed value is 31,622,400s (1 year). If not
specified, Cloud CDN uses 3600s (1 hour) for CACHE_ALL_STATIC mode.
Cannot exceed maxTtl. Cannot be specified when cacheMode is
USE_ORIGIN_HEADERS.
