Static delivery & SSG

How Nexora captures pages, serves flat HTML before PHP boots, and invalidates on publish.

Nexora Engine is not a one-time static export. It maintains a live WordPress backend while pre-rendering HTML snapshots that the drop-in serves before WordPress, PHP, or the database load.

Static site generation (SSG)

When you publish or bulk-regenerate, Nexora issues an internal loopback request signed with HMAC-SHA256. The response DOM is written atomically to disk so visitors always receive a complete file or the previous snapshot.

Free vs Pro rebuilds

On the free version, any change to a page, post, or public category/tag is tracked and added to a Pending list, you rebuild the mirror with one click from Static Delivery. Pro adds automatic rebuild on publish and update, so every change mirrors in the background with no manual step.

advanced-cache.php drop-in

The drop-in intercepts anonymous GET requests, checks for a valid snapshot, and streams it with ~22ms TTFB. Authenticated editors, cart sessions, and dynamic endpoints bypass the cache automatically.

Cache invalidation

  • save_post triggers debounced regeneration (30s coalescing for bulk edits)
  • Manual purge available per URL or site-wide from Build Control
  • WP-CLI commands for scripted invalidation in CI/CD
