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 (normally at var/log/system.log).

Visit the problematic pages/categories in your browser, and then check the log:

cd var/log
grep -Ri "route not cacheable" litemage.log

You may see something like the following:

2017-10-24T18:01:43+00:00 DEBUG (7): LiteMage [198.41.235.82:30180:84549400] ****** PRECHECK route_action [mana_attributePage_view] /brand NO_CACHE=route not cacheable

The log entries indicate that the routes brand_brand_index and brand_brand_view, or mana_optionPage_view and mana_attributePage_view, are not in the system default-enabled cache routes and should be added manually.

Navigate to LiteMage Config > User-Defined Cache Rules > Cacheable Routes and add the missing routes: brand_brand_view and brand_brand_index, mana_optionPage_view and mana_attributePage_view, or similar views as indicated by the debug log.

Issues can still arise after completing the above steps if the URL is not a standard category or product page, because the cached URLs may 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 Caching Additional URLs for more details.
