set_expire_access
Description:
Set the cache expiration policy for access times.
Items in the cache which haven't been accessed for when seconds may be expired at any time. Items are expired in a lazy manner, so
it is indeterminate when the items will physically be removed.
Note you can set both an age and an access limit. The age acts as a hard limit on cache entries.
Parameters:
| this | |
| when |
Timeout for access, or -1 to disable access expiry. |
