How to setup crawler cron job for LSCJoomla

In the latest LSCJoomla, it provides an crawler function at Advancded → Web interface to rebuild all LiteSpeed Cache:

Web interface to rebuild all LiteSpeed Cache: https://yourdomain.com/index.php?option=com_lscache&recache=5dcfad26ad657984064c731ee774a57f

To run the above crawler, your curl_exec cannot be disabled in your php.ini setting. Also you will need to enable crawler feature on LSWS which is most likely disabled on shared hosting server by default.

You can click Web interface to rebuild all LiteSpeed Cache link to run the crawler manually. It will only run once until completion.

To setup crawler as a cron job, you can simply wget the cachelink URL (please replace the URL with your own value):

wget https://yourdomain.com/index.php?option=com_lscache&recache=5dcfad26ad657984064c731ee774a57f

For example, setup the above cron job daily to run at 0:00, in crontab -e user:

0 0 * * * wget wget https://yourdomain.com/index.php?option=com_lscache&recache=5dcfad26ad657984064c731ee774a57  

The Homepage Public Cache TTL (minutes) defines how long the cache will be expired. The default settings for it is 2000 minutes, which is around 33 hours.

To keep the page cached most of the time, you can either set longer TTL to make the cache stay longer, or run the crawler periodically before the cache expired TTL. For example, for 2000 minutes TTL, running the crawler cron daily will keep the pages cached all the time.
