+Improve HTTP/2 request handling and error management in the proxy request handler; add try-catch around routing and update header processing to support per-backend protocol overrides.
+
+- Wrapped the routing call (router.routeReq) in a try-catch block to better handle errors and missing host headers.
+- Returns a 500 error and increments failure metrics if routing fails.

+
+## 2025-04-19 - 7.1.0 - feat(core)
+Add backendProtocol option to support HTTP/2 client sessions alongside HTTP/1. This update enhances NetworkProxy's core functionality by integrating HTTP/2 support in server creation and request handling, while updating plugin exports and documentation accordingly.
+
+- Introduced 'backendProtocol' configuration option (http1 | http2) with default 'http1'.
+- Updated creation of secure server to use http2.createSecureServer with HTTP/1 fallback.
+- Enhanced request handling to establish HTTP/2 client sessions when backendProtocol is set to 'http2'.

+
 ## 2025-04-04 - 7.0.0 - BREAKING CHANGE(redirect)
 Remove deprecated SSL redirect implementation and update exports to use the new redirect module

+# SmartProxy Project Hints
+
+## Project Overview
+- Package: `@push.rocks/smartproxy` – high-performance proxy supporting HTTP(S), TCP, WebSocket, and ACME integration.
+- Written in TypeScript, compiled output in `dist_ts/`, uses ESM with NodeNext resolution.
+
+## Repository Structure
+- `ts/` – TypeScript source files:
+  - `index.ts` exports main modules.
+  - `plugins.ts` centralizes native and third-party imports.
+  - Subdirectories: `networkproxy/`, `nftablesproxy/`, `port80handler/`, `redirect/`, `smartproxy/`.
+  - Key classes: `ProxyRouter` (`classes.router.ts`), `SmartProxy` (`classes.smartproxy.ts`), plus handlers/managers.
+- `dist_ts/` – transpiled `.js` and `.d.ts` files mirroring `ts/` structure.
+- `test/` – test suites in TypeScript:
+  - `test.router.ts` – routing logic (hostname matching, wildcards, path parameters, config management).
+  - `test.smartproxy.ts` – proxy behavior tests (TCP forwarding, SNI handling, concurrency, chaining, timeouts).
+  - `test/helpers/` – utilities (e.g., certificates).
+- `assets/certs/` – placeholder certificates for ACME and TLS.
+
+## Development Setup
+- Requires `pnpm` (v10+).
+- Install dependencies: `pnpm install`.
+- Build: `pnpm build` (runs `tsbuild --web --allowimplicitany`).
+- Test: `pnpm test` (runs `tstest test/`).
+- Format: `pnpm format` (runs `gitzone format`).
+
+## Testing Framework
+- Uses `@push.rocks/tapbundle` (`tap`, `expect`, `expactAsync`).
+- Test files: must start with `test.` and use `.ts` extension.
+- Run specific tests via `tsx`, e.g., `tsx test/test.router.ts`.
+
+## Coding Conventions
+- Import modules via `plugins.ts`:
+  ```ts
+  import * as plugins from './plugins.ts';
+  const server = new plugins.http.Server();
+  ```
+- Reference plugins with full path: `plugins.acme`, `plugins.smartdelay`, `plugins.minimatch`, etc.
+- Path patterns support globs (`*`) and parameters (`:param`) in `ProxyRouter`.
+- Wildcard hostname matching leverages `minimatch` patterns.
+
+## Key Components
+- **ProxyRouter**
+  - Methods: `routeReq`, `routeReqWithDetails`.
+  - Hostname matching: case-insensitive, strips port, supports exact, wildcard, TLD, complex patterns.
+  - Path routing: exact, wildcard, parameter extraction (`pathParams`), returns `pathMatch` and `pathRemainder`.
+  - Config API: `setNewProxyConfigs`, `addProxyConfig`, `removeProxyConfig`, `getHostnames`, `getProxyConfigs`.
+- **SmartProxy**
+  - Manages one or more `net.Server` instances to forward TCP streams.
+  - Options: `preserveSourceIP`, `defaultAllowedIPs`, `globalPortRanges`, `sniEnabled`.
+  - DomainConfigManager: round-robin selection for multiple target IPs.
+  - Graceful shutdown in `stop()`, ensures no lingering servers or sockets.
+
+## Notable Points
+- **TSConfig**: `module: NodeNext`, `verbatimModuleSyntax`, allows `.js` extension imports in TS.
+- Mermaid diagrams and architecture flows in `readme.md` illustrate component interactions and protocol flows.
+- CLI entrypoint (`cli.js`) supports command-line usage (ACME, proxy controls).
+- ACME and certificate handling via `Port80Handler` and `helpers.certificates.ts`.
+
+## TODOs / Considerations
+- Ensure import extensions in source match build outputs (`.ts` vs `.js`).
+- Update `plugins.ts` when adding new dependencies.
+- Maintain test coverage for new routing or proxy features.
+- Keep `ts/` and `dist_ts/` in sync after refactors.

+## Configuration Options
+
+### backendProtocol
+
+Type: 'http1' | 'http2' (default: 'http1')
+
+Controls the protocol used when proxying requests to backend services. By default, the proxy uses HTTP/1.x (`http.request`). Setting `backendProtocol: 'http2'` establishes HTTP/2 client sessions (`http2.connect`) to your backends for full end-to-end HTTP/2 support (assuming your backend servers support HTTP/2).
+
+Example:
+```js
+import { NetworkProxy } from '@push.rocks/smartproxy';
+
+const proxy = new NetworkProxy({
+  port: 8443,
+  backendProtocol: 'http2',
+  // other options...
+});
+proxy.start();
+```
 - **Basic Authentication** - Support for basic auth on proxied routes
 - **Connection Management** - Intelligent connection tracking and cleanup with configurable timeouts
 - **Browser Compatibility** - Optimized for modern browsers with fixes for common TLS handshake issues
