Crawls your website-pages based on any XML sitemap. If you have a caching plugin this will keep your cache warm.
Speeds up your site.
Compatible with following elements: < sitemap > < url >
All urls in your sitemap will be visited by the plugin to keep the cache up to date.
Will show average page load times and pages visited.
Needs google XML sitemap to read the generated XML file.
Needs a cronjob (wget or curl) to call the plugin. You need to setup the cronjob yourself! (Or ask your sysadmin to help you).

- Upload directory
- Activate the plugin through the ‘Plugins’ menu in WordPress.
- Visit Plugins menu to view your Warm cache options.
- Run a cronjob. See the menu for the cronjob URL.
Run it as often as you like, preferably more often then your
page cache expiration time.
Example: Page cache expiration = 1 hour, so set your cronjob at 30 minutes.
Set it higher when you have lots of pages
I have a BIG sitemap that takes over 5 seconds to load
use a filter called ‘http_request_timeout’
I have multiple (language / domain) sitemaps, but I can only add one sitemap!
Use a sitemap index, pointing to all your (custom/sub)-sitemaps. Only add the sitemap main index file to the plugin. Do NOT have this in the custom file name:
warmcache-sitemap.xml OR warmcache. Use this for example: supersitemap.xml or my_cache_sitemap.xml
How to disable logging completely (for very large sites)?
Set a define in your wp-config (at the top, newline, after <?php ) with name MP_WARM_CACHE_NO_LOGGING_AT_ALL and value “yes”

How to run a cronjob?
Ask your webhost how to set up a get call using wget or curl. See Installation for instructions howmany times you should call the cronjob.
The plugin shows an error, it cannot read the XML sitemap
The fact that you are able to “see” the XML in your browser does not guarantee that PHP is able to read it too.
Consult your host about this, if that fails.
Sucuri / Audit log notifies about new posts beeing created
We use the hidden post type warmcache to store statistics. We also remove them upon each crawl.
Feel free to ignore creation of posts with warmcache.
I have set up the cronjob but the stats table on the plugin page remains empty.
