We are pleased to announce that AdguardPrivate now fully supports the HTTP/3 protocol. All existing users will automatically be upgraded to enjoy the performance improvements brought by HTTP/3, without any additional configuration required.
Important Update Notes
- iOS Users: You can now use HTTP/3 directly through the DoH protocol, enjoying lower network latency
- Android Users: Due to system limitations, the DoT protocol is still in use, but support for HTTP/3 will be available after Google’s future updates
- Performance Improvement: The initial response time is significantly improved compared to HTTP/2, with faster connection establishment
- Smart Switching: In network environments that do not support HTTP/3, the system will automatically switch to HTTP/2 to ensure service stability
In-Depth Analysis of HTTP/3 Technology
HTTP/3, as the latest version of the HTTP protocol, is based on Google’s QUIC transport protocol and brings several innovative technical advantages:
Core Features
QUIC Protocol Based on UDP
- Significantly reduces connection establishment time
- Improved multiplexing capabilities
- More intelligent packet loss handling mechanism
Optimized Performance
- Zero handshake delay (0-RTT)
- Improved congestion control
- Support for connection migration
Enhanced Security
- Integrated with TLS 1.3
- Encrypted handshake process
- Reduced risk of man-in-the-middle attacks
Connection Process Comparison
Usage Recommendations
- Ensure your client supports the HTTP/3 protocol
- Keep your client version updated
- In restricted network environments, the system will automatically downgrade to HTTP/2
Precautions
- Network traffic in some regions may restrict UDP, affecting HTTP/3 performance
- Performance may vary in different network environments
- The system will automatically select the optimal protocol based on network conditions
