OpenRasta是否支持HEAD HTTP方法?

我正在尝试配置OpenRasta资源来响应HTTP HEAD操作。我已经尝试使用UriName，不同的方法名称和签名，但我找不到解决方案。这是我使用的配置代码:

ResourceSpace.Has.ResourcesOfType<Stream>()
                 .AtUri("/assets/{providerCode}/?type={type}")
                 .HandledBy<AssetHandler>();

这是AssetHandler的方法:

[HttpOperation(HttpMethod.HEAD)]
public OperationResult Head(string providerCode, int type)
{
    var asset = assetService.GetAssetAtCDN(providerCode, type);
    if (asset == null) return new OperationResult.NotFound();
    return new OperationResult.Found { RedirectLocation = new Uri(asset.Url) };
}

样本要求:

HEAD http://localhost:63483/assets/PygvCaOfK353etajBlbd/?type=4 HTTP/1.1
Accept-Encoding: gzip,deflate
Host: localhost:63483

反应:

HTTP/1.1 405 Method Not Allowed
Server: ASP.NET Development Server/9.0.0.0
Date: Mon, 31 Oct 2011 17:40:39 GMT
X-AspNet-Version: 2.0.50727
Cache-Control: private
Content-Length: 0
Connection: Close

和OpenRasta日志:

这是web.config的干净版本:
