Full Support for HTTP/3 Protocol

NullPrivate has fully implemented support for the HTTP/3 protocol. All existing users will be automatically upgraded to enjoy the performance improvements brought by HTTP/3 without requiring any additional configuration.

Important Update Notes

• iOS Users: Can now directly use HTTP/3 via DoH protocol for lower network latency
• Android Users: Due to system limitations, DoT protocol is still used; support will be added after future Google updates
• Performance Improvement: Significantly faster initial response time compared to HTTP/2 with quicker connection establishment
• Smart Fallback: Automatically switches to HTTP/2 in network environments without HTTP/3 support to ensure service stability

In-depth Technical Analysis of HTTP/3

As the latest version of the HTTP protocol, HTTP/3 brings multiple revolutionary technical advantages based on Google’s QUIC transport protocol:

Core Features

1. QUIC Protocol over UDP

   • Significantly reduces connection establishment time
   • Improved multiplexing capabilities
   • Smarter packet loss handling mechanisms

2. Optimized Performance

   • Zero round-trip time (0-RTT)
   • Enhanced congestion control
   • Connection migration support

3. Enhanced Security

   • Integrated TLS 1.3
   • Encrypted handshake process
   • Reduced risk of man-in-the-middle attacks

Connection Establishment Comparison

Usage Recommendations

• Ensure your client supports HTTP/3 protocol
• Keep client software updated
• System will automatically downgrade to HTTP/2 in restricted network environments

Important Considerations

• Some regional networks may restrict UDP traffic, affecting HTTP/3 performance
• Performance may vary across different network environments
• System automatically selects optimal protocol based on network conditions
