Keep your cache warm, permanently and optionally integrate with Varnish.

Sitemap crawler #

CacheMonster includes a controller action called crawlAndWarm that does two things; first it clears the entire Craft cache and then it crawls your xml site-map for urls and performs one GET request on all of them. This is publicly accessible and can be accessed using a url of the form See the Craft docs for more information on how to use controller actions directly.

It is mostly useful when used with CRON. For example, I want to purge all of Varnish and then run this action every night at half 1 in the morning:

30 1 * * * (/etc/init.d/varnish restart > /dev/null 2>&1; sleep 45; /usr/bin/curl --silent -H "X-Requested-With:XMLHttpRequest"

I have included a 45s sleep in this example as often you want to make sure Varnish has finished restarting.

Currently the sitemap must live at /sitemap.xml, in the future I hope to add various settings to allow you to override this.
