Offline Pages

Offline Pages plugin allows you to cache your entire WordPress site locally on iPad, iPhone, or Mac, then browse it while working offline, e.g. in Airplane Mode or when there is no network connection available. The plugin works in tandem with Offline Pages Pro or similar app. Together they efficiently synchronize your WordPress articles with on-device cache to provide a complete offline browsing experience for the entire site.

The plugin itself does not offer any useful functionality without the app. All it does is output a <link> element pointing to a special URL which serves XML document with rules for synchronizing your site, e.g. /blog/wp-admin/admin-ajax.php?action=opwp_rules. The URL is ignored by any browser except Offline Pages app which uses it as a guide to crawl the site and cache the resources according to rules contained in a document.

Rules Document

Unlike HTML5 cache manifest, Offline Pages rules documents don’t require listing every individual resource used by the website. Instead, they provide high-level instructions only. Examples of instructions are: block or allow certain URL patterns, customize caching policy, set update frequency, or add resource dependencies not recognizable automatically by crawler (e.g. when URLs are computed by non-trivial JavaScript expressions).

You can find rules document DTD here.
