HTTP/3

Introduction

YARP 1.1 supports HTTP/3 for inbound and outbound connections using the HTTP/3 support in .NET 7. To enable the HTTP/3 protocol in YARP you need to:

Configure inbound connections in Kestrel Configure outbound connections in HttpClient

Set up HTTP/3 on Kestrel

Protocols are required in the listener options:

C#   var builder = WebApplication.CreateBuilder(args);
   builder.WebHost.ConfigureKestrel(kestrel =>
   {
          kestrel.ListenAnyIP(443, portOptions =>
          {
                 portOptions.Protocols = HttpProtocols.Http1AndHttp2AndHttp3;
                 portOptions.UseHttps();
          });
   });
