YARP 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:

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

HttpClient

The default version of HttpRequest should be replaced by "3", find more details about HttpRequest configuration.
