Expiry time

The expiry time determines how long the page is stored in a cache.

HCL allows three options for specifying expiry time:
Cache always expires
The content is never cached in either a shared or a private cache; set the remote cache expiry to 0.
Cache never expires
The content can be stored indefinitely in either a shared or a private cache; set the remote cache expiry to -1.
Cache expires after this many seconds
The content is stored for the number of seconds specified in either a shared or a private cache; set the remote cache expiry to a positive integer up to 2^31 -1.
