Global cache storage configuration

Controls the underlying storage backend for HTTP caching. This is separate from per-route cache policies which control what gets cached and for how long.

Fields

enabled: bool

Enable HTTP caching globally (default: true when cache block is present)

backend: CacheBackend

Storage backend type

max_size_bytes: usize

Maximum cache size in bytes (default: 100MB)

eviction_limit_bytes: Option<usize>

Eviction limit in bytes (when to start evicting, default: same as max_size)

lock_timeout_secs: u64

Cache lock timeout in seconds (prevents thundering herd)

disk_path: Option<PathBuf>

Path for disk-based cache (only used with Disk backend)

disk_shards: u32

Number of shards for disk cache (improves concurrent access)

disk_max_size_bytes: Option<usize>

Maximum size for the disk tier in hybrid mode (defaults to max_size_bytes)

status_header: bool

Add Cache-Status response header (RFC 9211) for cache observability
