LiteSpeed Cache for Prestashop: Crawler

The crawler travels through your site, refreshing pages that have expired in the cache. This makes it less likely that your visitors will encounter un-cached pages.

1. Install and enable LiteSpeed Cache for Prestashop
2. Crawler Engine: The crawler must be enabled at the server level, or you will see the warning message Server crawler engine not enabled. Please check….. If you are using a shared hosting server, please contact your hosting provider, or see our instructions.
3. SiteMap: Prepare your site's sitemap, e.g. http://prestashop-123/456_sitemap.xml

The Google Sitemap module is quite popular for generating a sitemap in Prestashop, and it's much faster than online generation.

For v1.6, Google Sitemap Module is installed by default.

For v1.7+, Google Sitemap Module needs to be installed from source first. Download gsitemap; then change the file name to gsitemap.zip.

Click the Configure button, you will see e.g. xxx/1_index_sitemap.xml(This is your main SITE-MAP-URL, ).

One of the popular sitemap generators is XML-Sitemaps.com After the crawl is finished. Click DOWNLOAD YOUR XML SITEMAP FILE and put it where the crawler script can access it.

How often do we want to re-initiate the crawling process? This depends on how long it takes to crawl your site and what did you set for Public Cache TTL.
Default TTL is one day(24hr). Maybe you can consider to run the script by cronjob every 12 hours.
E.g. This will run twice a day, at 3:30am/15:30: 30 3/15 * * * path_to_script/cachecrawler.sh SITE-MAP-URL -m -i 0.2

Note: You can also use online crontab tool help you to verify time settings.

By using the browser developer tool, you should see X-LiteSpeed-Cache: hit at the first view for both desktop and Mobile
