Expiry time

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

WebSphere Portal 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.
