-====== LiteSpeed Cache for Magento2: Crawler ======
+~~REDIRECT>https://docs.litespeedtech.com/lscache/litemage/settings/#cache-warmup~~
-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.
-===== Before You Begin =====
-  - Install and enable [[https://www.litespeedtech.com/support/wiki/doku.php/litespeed_wiki:cache:litemage2:installation | LiteMage Cache for Magento2]]
-  - 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 [[litespeed_wiki:cache:lscwp:configuration:enabling_the_crawler|our instructions]].
-  - SiteMap: Prepare your site's sitemap, e.g. ''<nowiki>http://magento2.com/sitemap.xml</nowiki>''
-===== How to Use the Crawler Script=====
-  -[[https://www.litespeedtech.com/packages/litemage2.0/M2-crawler.sh | Download from here]]
-  - Change the permissions so that the file is executable: ''chmod +x M2_crawler.sh''
-  - Run the script: ''bash M2-crawler.sh SITE-MAP-URL''
-==== More Options====
-  * ''-h, --help'': Show this message and exit.
-  * ''-m, --with-mobile'': Crawl mobile view in addition to default view.
-  * ''-c, --with-cookie'': Crawl with site's cookies.
-  * ''-b, --black-list'': Page will be added to blacklist if HTML status error and no cache. Next run will bypass page.
-  * ''-g, --general-ua'': Use general user-agent instead of lscache_runner for desktop view.
-  * ''-i, --interval'': Change request interval. ''-i 0.2'' changes from default 0.1 second to 0.2 seconds.
-  * ''-v, --verbose'': Show complete response header under ''/tmp/crawler.log''.
-  * ''-d, --debug-url'': Test one URL directly. as in ''sh M2-crawler.sh -v -d http://example.com/test.html''.
-  * ''-qs,--crawl-qs'': Crawl sitemap, including URLS with query strings.
-  * ''-r, --report'': Display total count of crawl result.
-Example commands:
-  * To get help: ''bash M2-crawler.sh -h''
-  * To change default interval request from 0.1s to custom NUM value: ''bash M2-crawler.sh SITE-MAP-URL -i NUM''
-  * To crawl with cookie set: ''bash M2-crawler.sh -c SITE-MAP-URL''
-  * To store log in ''/tmp/crawler.log'': ''bash M2-crawler.sh -v SITE-MAP-URL''
-  * To debug one URL and output on screen: ''bash M2-crawler.sh -d SITE-URL''
-  * To display total count of crawl result: ''bash M2-crawler.sh -r SITE-MAP-URL''

-===== How to Generate a Sitemap=====
-Magento 2 has a builtin module for generating a sitemap and it's fast.
-==== Enable sitemap ====
-Navigate to **Magento Admin > Stores > Settings > Configuration > Catalog > XML Sitemap**
-{{:litespeed_wiki:cache:litemage2:m2-4.png?600|}}
-Set **Generation Settings > Enabled** to ''Yes''
-{{:litespeed_wiki:cache:litemage2:m2-5.png?600|}}
-==== Configuring a Single Sitemap for All Storefronts ====
-Navigate to **Magento Admin > Marketing > Seo & Search > Sitemap**
-  - Click the **Add Sitemap** button
-  - Enter values
-    * **Filename**: ''sitemap.xml''
-    * **Path**: ''/''
-  - Click the **Save & Generate** button
-{{:litespeed_wiki:cache:litemage2:m2-2.png?600|}} \\
-If all went well, a ''sitemap.xml'' file will have been generated in your Magento 2 document root.
-===== Crawl Interval =====
-How often do you want to re-initiate the crawling process? This depends on how long it takes to crawl your site and what you set for Public Cache TTL.
-The default TTL is one day(24hr). Maybe, for example, you'd like to run the script by cronjob every 12 hours instead.
-E.g. This will run twice a day, at 3:30am/15:30: ''30 3/15 * * * path_to_script/M2_crawler.sh SITE-MAP-URL -m -i 0.2''
-Note: You can also use [[https://crontab.guru/|online crontab tool]] to help you to verify the time settings.
-===== Run crawler after any product update on Magento 2 =====
-In Magento 2, any product update will trigger all caches purged by the design of Magento 2. LiteMage doesn't have any control of this Magento 2 designed behavior.  Hence you may find pages uncached even you run above crawl interval less than TTL. It doesn't mean LiteMage 2 doesn't work well or Crawler doesn't work well. It is simply a Magento 2 design matter.
-To avoid above situation, we would recommend you schedule a specific windows to do any product changes through Magento admin. For example, two hours from 6:00pm to 8:00pm offpeak time. Then you run the crawler immediately after the change.
-===== How to Verify the Crawler is Working =====
-When using [[https://developers.google.com/web/tools/chrome-devtools/|the browser developer tool]], load a previously uncached page. You should see ''X-LiteSpeed-Cache: hit,litemage'' on the first view.
