Expand description

Configuration for creating a proxy

Fields§

§proxy_url: String

The backend URL to proxy requests to

§include_paths: Vec<String>

Paths to include in caching (empty means include all) Supports wildcards and method prefixes: “/api/”, “POST /api/”, “GET /*/users”, etc.

§exclude_paths: Vec<String>

Paths to exclude from caching (empty means exclude none) Supports wildcards and method prefixes: “/admin/*”, “POST ”, “PUT /api/”, etc. Exclude overrides include

§enable_websocket: bool

Enable WebSocket and protocol upgrade support (default: true) When enabled, requests with Connection: Upgrade headers will bypass the cache and establish a direct bidirectional TCP tunnel

§forward_get_only: bool

Only allow GET requests, reject all others (default: false) When true, only GET requests are processed; POST, PUT, DELETE, etc. return 405 Method Not Allowed Useful for static site prerendering where mutations shouldn’t be allowed

§cache_key_fn: Arc<dyn Fn(&RequestInfo<'_>) -> String + Send + Sync>

Custom cache key generator Takes request info and returns a cache key Default: method + path + query string

§cache_404_capacity: usize

Capacity for special 404 cache. When 0, 404 caching is disabled.

§use_404_meta: bool

When true, treat a response containing the meta tag <meta name="phantom-404" content="true"> as a 404 This is an optional performance-affecting fallback to detect framework-generated 404 pages.

§cache_strategy: CacheStrategy

Controls which responses should be cached after the backend responds.

§compress_strategy: CompressStrategy

Controls how cached bodies are stored in memory.

§cache_storage_mode: CacheStorageMode

Controls where cached response bodies are stored.

§cache_directory: Option<PathBuf>

Optional override for filesystem-backed cache bodies.

§proxy_mode: ProxyMode

Controls the operating mode of the proxy (Dynamic vs PreGenerate/SSG).

§webhooks: Vec<WebhookConfig>

Webhooks called for every request before cache reads. Blocking webhooks gate access; notify webhooks are fire-and-forget.
