Features

• HTTP Request Handling - Provides a high-performance handler for processing concurrent HTTP, HTTPS, and UNIX socket requests.
• High-Performance HTTP Servers - Ships a zero-allocation HTTP server library optimized for maximum throughput and minimal garbage collection overhead.
• HTTP Clients - Manages reusable network clients with custom connection pooling, timeouts, and retry policies.
• Networking Frameworks - Provides a collection of low-level primitives for building scalable web servers and clients with optimized memory management.
• Asynchronous Request Handlers - Provides a high-concurrency request processing engine designed for performance-critical web applications.
• In-Memory Connection Bypassing - Bypasses the network stack to connect clients and servers within the same process for minimal latency.
• Object Pooling - Recycles temporary request and response objects through managed pools to minimize memory allocation and garbage collection pressure.
• HTTP Client Configurations - Configures reusable clients with custom policies for redirects, timeouts, and connection pooling.
• Connection Establishment Protocols - Provides mechanisms for upgrading standard HTTP connections to persistent protocols like WebSockets.
• High-Concurrency Networking - Distributes socket connections across multiple CPU cores to maximize throughput under heavy load.
• Load Balancers - Distributes incoming requests across multiple backend services or CPU cores to maximize throughput.
• Zero-Allocation Conversions - Performs byte-to-string conversions without memory allocations to minimize garbage collection pressure.
• Zero-Copy Mechanisms - Transforms byte slices into strings using unsafe memory pointers to avoid redundant memory allocations.
• Networking Libraries - High-performance HTTP implementation.
• Networking - High-performance HTTP implementation.
• Networking and Protocols - High-performance HTTP implementation for fast web services.
• Networking Libraries - High-performance HTTP implementation.
• Routing and Middleware - High-performance HTTP package optimized for zero memory allocation.
• Web Frameworks - High-performance HTTP implementation for low-latency services.
• Concurrent Map Implementations - Provides thread-safe key-value structures optimized for high-concurrency access.
• Graceful Shutdowns - Ensures clean termination by allowing active requests to complete before shutting down the server.
• HTTP Transport Configurations - Provides utilities for customizing network transport behavior including connection pooling and request timeouts.
• WebSocket Connection Verifiers - Allows handlers to take control of network connections after HTTP responses for custom protocol implementation.
• Request Size Limiters - Protects server stability by capping concurrent connections, request sizes, and execution times.
• Thread-Per-Core Architectures - Distributes incoming network connections across multiple CPU cores to maximize throughput and minimize latency.
• Request Timeouts - Enforces execution limits on request handlers to prevent resource exhaustion from hanging connections.
• Protocol Upgrades - Facilitates the transition of standard HTTP connections to persistent bidirectional communication channels.
• HTTP/2 Protocol Implementations - Implements modern protocol features to improve performance and concurrency for network communication.
• CSRF Protection - Validates cross-origin requests by checking security headers or origin hostnames to block unauthorized actions.
• HTML Template Renderers - Parses and executes HTML templates with automatic contextual escaping to prevent injection attacks.
• HTTP Handler Adapters - Adapts standard library request handlers for use within high-performance server environments.
• Response Compression - Reduces bandwidth usage by compressing network responses using Gzip, Deflate, or Brotli.
• Static Asset Management - Serves files from the local filesystem with automatic compression and optimized header management.
• Static File Servers - Delivers static files from the filesystem with automatic handling of MIME types and range requests.
• Request Retries - Automatically re-attempts failed network requests based on idempotency rules to improve reliability.
• Response Streaming - Flushes buffered data to the client incrementally during request processing to provide real-time updates.
• In-Memory Network Bypasses - Enables direct in-process communication between clients and servers to reduce network latency.
• Load Balancers - Distributes incoming requests among multiple backend clients using a least-loaded strategy.
• Mutual Exclusion Locks - Uses mutual exclusion locks to ensure safe access to critical sections of code or data.
• Task Schedulers - Implements task orchestration mechanisms to monitor and synchronize the completion of concurrent operations.
• Server Metrics - Exposes internal application metrics as JSON over HTTP for monitoring and observability.
• Query Parameter Parsers - Parses and organizes URL-encoded query strings into structured key-value maps.
