问为什么从ASP.NET中调用VBScript ASHX处理程序时会得到.NET中的“无法创建SSL/TLS安全通道”错误？

EN

using System.Net;

public class Test
{
    const string theUrl = "https://www.example.com/Handler.ashx?ID=123";
    public static void Main(string[] args)
    {
        var req = WebRequest.Create(theUrl);
        var resp = req.GetResponse();
    }
}

Const theUrl = "https://www.example.com/Handler.ashx?ID=123"

Dim oXmlHttp

Set oXmlHttp = WScript.CreateObject("Microsoft.XMLHTTP")
With oXmlHttp
    .Open "GET", theUrl, False
    .Send

    WScript.Echo CStr(.Status)
End With

Set oXmlHttp = Nothing
