- Serve cache via template_redirect so feeds/404/REST are excluded and
query conditionals work
- Bypass cache on query strings; key files by md5(host+path) to avoid
collisions and support multisite
- Write wp-content/wp-recache-cache.php drop-in server and set WP_CACHE
in wp-config.php so advanced-cache.php actually runs
- Only remove advanced-cache.php on deactivation when it is ours
- Respect DONOTCACHEPAGE, non-200 responses; bots read but never warm
cache
- Fix comment purge (comment_post_ID) and heartbeat purge ($data arg)
- Fix exclude URLs textarea parsing; purge all when exclusions change
- Enqueue admin purge script on every admin-bar page, not just settings
- Sync tests, add TESTING.md manual test guide
