v1.6.0

This update brings significant improvements to HTTP engine architecture, a new file server system, and framework enhancements.

HTTP File Server

Introduced the new HttpFileServer system for serving static files efficiently and flexibly:

• Optimized streaming with Range header support for audio and video
• Customizable converters through HttpFileServerFileConverter
• Configurable directory listing
• Automatic content negotiation based on MIME types

var route = HttpFileServer.CreateServingRoute("/static", "./public");
router += route;

// Or with custom configuration
var handler = new HttpFileServerHandler("./public") {
    AllowDirectoryListing = true,
    // Add custom converters
};
var route = HttpFileServer.CreateServingRoute("/files", handler);

The new FileContent class allows returning files with automatic streaming and range request support:

router.SetRoute(RouteMethod.Get, "/download", request => {
    return new FileContent("./video.mp4");
});

The HttpFileAudioConverter and HttpFileVideoConverter converters provide automatic support for range requests in media files, enabling seeking in audio/video players.

HTTP Engine Improvements

Significant improvements to HTTP engine abstraction:

• Nova interface HttpServerEngineContext: Abstração completa do ciclo de vida de requisições HTTP
• HttpServerEngineWebSocket: Interface abstrata para WebSocket em diferentes engines
• Mecanismos de event loop: Suporte através de HttpServerEngineContextEventLoopMecanism
• Melhor integração SSL: Classe ListeningHostSslOptions para configuração SSL por listening host

var host = new ListeningHost("https://localhost:5000") {
    SslOptions = new ListeningHostSslOptions {
        Certificate = myCertificate
    }
};

Logging Improvements

• RotatingLogPolicyCompressor: Interface for automatic compression of rotated logs
• GZipRotatingLogPolicyCompressor: Built-in implementation with GZip compression
• PrefixedLogStream: Improvements to prefixed log stream

var rotatingPolicy = new RotatingLogPolicy {
    Compressor = new GZipRotatingLogPolicyCompressor()
};

HTTP Server Handler Improvements

• Handler execution ordering: Added Priority property to HttpServerHandler to control execution order
• HttpServerHandlerSortingComparer: New comparer for sorting handlers by priority (lower values execute first)
• HttpServerHandlerRepository: Changed internal storage from List<T> to SortedSet<T> for automatic priority-based ordering

WebSocket Improvements

• Fix: Corrections to WebSocket connection management
• Improvements to HttpWebSocketConnectionCollection
• Better handling of closed connections

Other Changes

• HttpRequestEventSource: Improvements to Server-Sent Events system
• CertificateHelper: New helper class for SSL certificate management
• HttpRequest.DisconnectToken: Improvements to disconnection detection
• HttpServerExecutionResult: New fields for better execution tracking

Breaking Changes

• ListeningHost: SSL properties moved to ListeningHostSslOptions
• HttpServerEngine: New interface with additional abstract methods
• Some method signatures in engines have been changed to support the new contexts

Bug Fixes

• Fixed: Simplified connection closed check in HTTP request parsing
• Fixed: HTTP body drainage corrected
• Fixed: Issues with chunked encoding in requests
• Fixed: Better abort handling in HTTP components
• Fixed: Optimized HTTP header parsing and handling
