Cache Time-To-Live

Cache Time-To-Live (TTL) specifies the duration, in minutes, that an entry in the cache is retained. When the TTL expires, the entry is removed and the next time that the user submits a request, the user is authenticated. If the authentication succeeds, an entry is placed in the cache.

The default TTL is 15 minutes. The range of valid values is 5 to 1440 minutes.
