 5. **Implement Route-Specific Security**: Add security checks when a route is matched to enforce route-specific IP allow/block lists and authentication rules. ✅ FIXED - IP allow/block lists are now enforced at the route level.
 
 6. **Fix TLS Detection Logic**: The connection handler was treating all connections as TLS. This has been partially fixed but needs proper testing for all TLS modes.
+
+## 7. HTTP Domain Matching Issue
+**Problem**: Routes with domain restrictions fail to match HTTP connections because domain information is only available after HTTP headers are received, but route matching happens immediately upon connection.
+**Evidence**: 
+- `test.http-port8080-forwarding.ts` - "No route found for connection on port 8080" despite having a matching route
+- HTTP connections provide domain info via the Host header, which arrives after the initial TCP connection
+- Route matching in `handleInitialData` happens before HTTP headers are parsed
+**Impact**: HTTP routes with domain restrictions cannot be matched, forcing users to remove domain restrictions for HTTP routes.
+**Root Cause**: For non-TLS connections, SmartProxy attempts to match routes immediately, but the domain information needed for matching is only available after parsing HTTP headers.
+**Status**: ✅ FIXED - Added skipDomainCheck parameter to route matching for HTTP proxy ports. When a port is configured with useHttpProxy and the connection is not TLS, domain validation is skipped at the initial route matching stage, allowing the HttpProxy to handle domain-based routing after headers are received.
+
+## 8. HttpProxy Plain HTTP Forwarding Issue
+**Problem**: HttpProxy is an HTTPS server but SmartProxy forwards plain HTTP connections to it via `useHttpProxy` configuration.
+**Evidence**: 
+- `test.http-port8080-forwarding.ts` - Connection immediately closed after forwarding to HttpProxy
+- HttpProxy is created with `http2.createSecureServer` expecting TLS connections
+- SmartProxy forwards raw HTTP data to HttpProxy's HTTPS port
+**Impact**: Plain HTTP connections cannot be handled by HttpProxy, despite `useHttpProxy` configuration suggesting this should work.
+**Root Cause**: Design mismatch - HttpProxy is designed for HTTPS/TLS termination, not plain HTTP forwarding.
+**Status**: Documented. The `useHttpProxy` configuration should only be used for ports that receive TLS connections requiring termination. For plain HTTP forwarding, use direct forwarding without HttpProxy.
