PHP.Bot Blogger now had complete caching, built into the core. Currently, the cache refreshes every 30 minutes, with plans to make this adjustable in the future. The Ajax-powered search functionality also benefits from dedicated caching, enhancing performance.
Additionally, I have developed a script that generates the HTML and RSS sitemaps by fully crawling the site. This process includes wiping the main cache beforehand, ensuring that as the sitemap is built, the cache is simultaneously refreshed, maintaining up-to-date content across the site.
