Cache features: Cache features:
- **LRU Index**: Tracks file access times and sizes for eviction - **proxy_cache**: nginx handles caching of GET/HEAD requests with 1-hour TTL
- **Eviction**: Removes least-recently-used entries when limit exceeded - **Slice module**: Large files cached in 1MB chunks for efficient range requests
- **TTL**: Expires entries after configured time (`CACHE_TTL_SECONDS`) - **TTL-based expiry**: Entries expire after 1 hour of inactivity
- **Invalidation**: Cache invalidator listens to Redis keyspace changes - **X-Cache-Status header**: Returns MISS/HIT/EXPIRED for debugging
- **Write bypass**: PUT/DELETE/MKCOL operations bypass cache
- **Directory Listing**: Returns JSON for programmatic access - **Directory Listing**: Returns JSON for programmatic access
