Unlocking QUIC’s proxying potential with MASQUE

What this post added

This post introduces MASQUE (Multiplexing And Secure Communication over QUIC Encapsulation) as a protocol that leverages QUIC's DATAGRAM frames to enable UDP tunneling. It explains how MASQUE, built on extended CONNECT requests, allows for proxying non-TCP applications like HTTP/3, addressing the limitations of TCP-based proxying and extending Cloudflare Tunnel's capabilities to handle a wider range of protocols and improve privacy through nested tunneling.
