Cache Explorer

The cache explorer lets you browse all cached content across ISR, fragment, and tenant caches.

Features

  • Cache browser — Tree view of all cached keys grouped by type (ISR, fragment, tenant)
  • Entry detail — View cached content, headers, TTL, stale-while-revalidate status
  • Manual invalidation — Purge individual entries or by tag/pattern
  • Stampede guard — Visual indicator when stampede prevention is active for a key
  • L1/L2 visualization — See which entries are in the in-memory L1 cache vs Redis L2
  • Hit/miss stats — Per-key access counts and cache hit ratio

Usage

  1. Connect to an instance
  2. Click Cache in the navigation
  3. Browse the cache tree or search by key pattern
  4. Click any entry to see its details, headers, and content preview
  5. Use the Purge button to invalidate a specific entry

Tag-based invalidation

If your app uses cache tags (e.g., blog-posts, user-123), you can invalidate all entries matching a tag:

  1. Click Purge by Tag in the toolbar
  2. Enter the tag name
  3. All entries with that tag are invalidated across L1 and L2

This mirrors the bext-server cache purge --tag <name> CLI command.

Tip

Tag-based invalidation only works if your routes set cache tags via the Cache-Tag response header or the bext caching API. Without tags, use pattern-based purge instead.
