====== ComboStrap Cache - Page Cache Expiration Frequency ======


===== About =====

The ''page cache expiration frequency'' is a [[docs:metadata:metadata|metadata]] that permits to
  * schedule the [[page|page cache]] expiration time
  * for only one page
  * based on a cron expression

===== Example =====

To refresh the cache of your page:
  * at midnight daily:
<code cron>
@daily
</code>
  * at 12:02 on Monday
<code cron>
02 12 * * 1
</code>
  * at midnight monthly:
<code cron>
@monthly
</code>


More examples can be seen on this [[https://crontab.guru/examples.html|page]].


===== Syntax =====

The value is a ''cron'' expression
  * named (''@daily'')
  * or in the full format

<code>
┌───────────── minute (0 - 59)
│ ┌───────────── hour (0 - 23)
│ │ ┌───────────── day of the month (1 - 31)
