Description

Controls whether Microsoft Edge uses the Happy Eyeballs V3 algorithm to optimize connection attempts. This algorithm improves reliability and performance in dual-stack (IPv4/IPv6) networks by racing connection attempts across IP versions and HTTP protocols (e.g., HTTP/3 vs. others). For more details, see https://datatracker.ietf.org/doc/draft-pauly-happy-happyeyeballs-v3.

Enabled: Uses the algorithm for connection attempts.

Disabled or not configured: Disables the algorithm.

Note: This policy supports dynamic refresh.
