C# CORS HttpChannel，如何提供正确的标头？

Google Chrome有一个向服务器发送XML-RPC数据的扩展。服务器XML-RPC是一个桌面.NET应用程序

以下是初始化服务器的代码：

Dim properties As IDictionary = New Hashtable

properties.Item("name") = "hostChannel"
properties.Item("port") = 5678

Dim chnl As New HttpChannel(properties, Nothing, New XmlRpcServerFormatterSinkProvider)

Try

    ChannelServices.RegisterChannel(chnl, False)

    RemotingConfiguration.RegisterWellKnownServiceType(GetType(StateNameServer), "statename.rem", WellKnownObjectMode.Singleton)
    RemotingConfiguration.RegisterWellKnownServiceType(GetType(CoderServer), "statename.rem", WellKnownObjectMode.Singleton)

Catch ex As Exception

    MessageBox.Show("Ошибка")

End Try

向该服务器发送ajax请求时，保护会使CORS无法正常工作，并导致外接程序出错

要使其工作，服务器必须提供正确的头。在浏览器的选项请求中，响应代码

对于基于Apache的web服务器，此问题已通过以下内容在域根目录中解决

Header set Access-Control-Allow-Origin "*"
Header always set Access-Control-Max-Age "1000"
Header always set Access-Control-Allow-Headers "X-Requested-With, Content-Type, Origin, Authorization, Accept, Client-Security-Token, Accept-Encoding"
Header always set Access-Control-Allow-Methods "POST, GET, OPTIONS, DELETE, PUT"

RewriteEngine On
RewriteCond %{REQUEST_METHOD} OPTIONS
RewriteRule ^(.*)$ blank.php [QSA,L]
