Why Are Some Pages Cached While Others Are Not?

After you enable LiteMage, you may see that most of the pages are cached but some are not. This sometimes happens with brand pages.

LiteMage has a default system-defined cachable route. Extra routes may need to be added for some pages in order to include them in the cache.

Please check the configuration of the system-defined cache route and the user-defined cache rules.

Enable the debug log and you may see something like the following:

 
2017-02-21T14:55:31+00:00 DEBUG (7): LiteMage [xx.xx.xx.xx:26072:29461700] ****** PRECHECK route_action [brand_brand_index] /brand/ NO_CACHE=route not cacheable
2017-02-21T15:30:21+00:00 DEBUG (7): LiteMage [xx.xx.xx.xx:37765:19171300] ****** ****** PRECHECK route_action [brand_brand_view] /brand/sorciere.html NO_CACHE=route not cacheable

This means that route is not in the system default-enabled cache route and should be added manually. Navigate to LiteMage Config > User-Defined Cache Rules > Cacheable Routes and add the following: brand_brand_view, brand_brand_index.

Issues can still arise after completing the above steps if the URL is not a standard category or product page, as the cached URLs will not be tagged properly. For example, if a product within the brand page is updated, the standard Magento categories and product pages will be auto-purged, but the brand page will not. To resolve this issue, define a custom warm-up URL list that will crawl these pages in more frequent intervals, such as every 30 minutes.

See Cachine Additional URLs for more details.
