PoweredCache generates static HTML files from your dynamic WordPress site. After an HTML file is generated your webserver will serve that file instead of processing the comparatively heavier and more expensive WordPress PHP scripts. Page caching is one of most important feature to decrease the load time of your website and making much faster.
Serving cached output without executing PHP script
PoweredCache can automatically manage .htaccess rules to serve cached files without executing PHP. In order to apply similar rules to Nginx, you can download the sample configuration under the “Misc” settings.
Cache related files:
- index.html : HTML output for a page without SSL
- index-https.html : HTML output for a page with SSL
- index-https.html.gz : HTMP output for a page with SSL and gzip activated
- meta.php: Stores header info
Depends on the configuration some you can see separate files for mobile caching or the dynamically generated index name when serving non HTML content, such as JSON API responses.
