0.5.0

👉 Dito 0.5.0 - WebSocket Proxy Support

What's New

WebSocket Proxy Support 🕸️

Dito now supports WebSocket proxying, allowing you to seamlessly forward WebSocket connections to your backend servers. This feature can be enabled per location, offering flexible and granular WebSocket routing for real-time applications and protocols.

  • Easily enable WebSocket support on specific routes by adding enable_websocket: true to your location configuration.
  • Example:

    # List of location configurations for proxying requests.
    locations:
       - path: "^/test-ws$" # Regex pattern to match the request path.
         target_url: "wss://echo.websocket.org" # The target URL to which the request will be proxied.
         enable_websocket: true # Enable WebSocket support for this location.
         replace_path: true # Replace the matched path with the target URL.

Upcoming Enhancements for WebSocket Support 🔄

Future versions of Dito will include even more advanced WebSocket features:

• Enhanced TLS Support: Configurable TLS settings for secure WebSocket connections, ensuring data integrity and privacy.
• Comprehensive Error Handling: Improved resilience and error management for WebSocket connections to handle unexpected interruptions or connection issues gracefully.
• Detailed Metrics: Real-time metrics for WebSocket traffic, allowing you to monitor performance, connection stability, and data flow with precision.

0.4.0

👉 Dito 0.4.0 - Custom Transport Configuration & Improved Logging

What's New

Custom Transport Configuration 🚀

• Per-Location HTTP Transport Settings: You can now customize the HTTP transport settings on a per-location basis. This allows for fine-grained control over backend connections, including timeouts, connection limits, and TLS settings.
  • Features Include:
    • Timeouts and Connection Limits: Configure idle_conn_timeout, max_idle_conns, max_conns_per_host, etc.
    • TLS Settings: Manage tls_handshake_timeout and enforce HTTP/2 if needed.
    • Custom Certificates: Specify cert_file, key_file, and ca_file for mTLS connections.

Improved Logging System

• Asynchronous Logging with Worker Pool: Logging operations are now handled asynchronously using a worker pool to prevent blocking the main request handling.
• Non-Blocking Log Channel: Implemented a non-blocking select statement to avoid blocking when the log channel is full.
• Configurable Buffer Size: You can now configure the size of the log channel buffer to balance memory usage and logging throughput.
• Performance Optimizations: Reduced memory allocations and improved logging efficiency to handle high-throughput scenarios.

Enhancements

• Stability Improvements: Enhanced the transport layer stability by caching transports and ensuring they are updated promptly after configuration changes.

Please test these updates in your environment and provide feedback.
Contributions and issue reports are appreciated.

0.3.1

👉 Dito 0.3.1 - Transport and Cache Fixes

What's New:

• Transport cache handling fix: Resolved an issue where the transport was not being updated immediately after configuration changes. Now, transports are updated promptly to ensure that all requests reflect the latest configuration.
• Cache middleware optimization: Improved the behavior of the cache middleware to handle transport updates correctly. This addresses delays in responses when caching is enabled.

Enhancements:

• Transport layer stability: Introduced caching for transports to enhance the stability and efficiency of the proxy.
• Performance improvements: Optimized the cache middleware to reduce latency, ensuring faster response times when serving cached responses from Redis.

How to Use:

1. Ensure that your configuration is up to date and that caching and transport settings are configured correctly in config.yaml.
2. Test the transport updates after configuration changes to ensure proper functionality.

Please test these updates in your environment and provide feedback.
Contributions and issue reports are appreciated.

0.3.0

👉 Dito 0.3.0 - Prometheus Metrics Support

What's New:

• Added Prometheus metrics support: Dito now exposes various metrics for monitoring the proxy's performance and behavior, including custom metrics for HTTP requests, duration, active connections, and data transfer.
• Standard Go and Prometheus metrics: Enabled automatic collection of Go runtime metrics (memory, garbage collection, goroutines) and Prometheus HTTP handler metrics.

Enhancements:

• Configurable metrics support: Metrics can be enabled or disabled via the config.yaml file. The default metrics path is /metrics.
• Detailed monitoring: Added custom metrics:
  • http_requests_total: Tracks the total number of HTTP requests processed.
  • http_request_duration_seconds: Measures the duration of HTTP requests.
  • active_connections: Indicates the number of active connections.
  • data_transferred_bytes_total: Monitors the amount of data transferred, partitioned by direction (inbound or outbound).

How to Use:

1. Enable metrics in the configuration:

   metrics:
      enabled: true
      path: "/metrics"
