What do I look for in HTML? For UCSS and cache, LiteSpeed leaves a comment at the bottom, not for CCSS<\/li>\n\n\n\n<li>In the article it says &#8220;The cron picks up the CCSS and saves it to be inserted into the HTML of all pages that have that post type next time those pages are cached&#8221;. Does it mean, I have to periodically clear LSCache so that CCSS changes are being picked up when page is cached?<\/li>\n<\/ol>\n","protected":false},"template":"","class_list":["post-19007068","topic","type-topic","status-publish","hentry"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/19007068","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic"}],"about":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/19007068\/revisions"}],"wp:attachment":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/media?parent=19007068"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
