Issue/Introduction

Does the WSS Proxy support the ALPN [2] protocol via HTTP/2 [3]?

Environment

WSS release SEPT.22.2022

Cause

The feature is available in Proxy SG [1] but not yet enabled in WSS

Resolution

The feature is currently planned to be enabled in the WSS October 2022 release.

The feature may be rolled out in phases so not all locations would be available to use http/2 / ALPN immediately after the October 2022 release.
