Update, support for this was added in actix-http v3.3: https://docs.rs/actix-http/latest/actix_http/struct.HttpService.html#method.tcp_auto_h2c This is true. Without some form of protocol negotiation like that this is provided by TLS ALPN then we cannot select an appropriate HTTP version to use. Inspecting bytes is possible but would be unnecessary overhead for all Actix Web servers. I do know it is possible to do at the user level but would need to dig up the code to make it work. |
