我们有一个在服务器上运行的 Web 应用程序，它通过 XDomainRequest 发布 http 请求（因为 IE9）。
有很多客户端计算机都有一个控制台应用程序通过套接字侦听器侦听端口。客户打开 Web 应用程序
IE9 浏览器，当他们单击链接时，网页会发送如下请求：
"https://localhost:端口号/应用程序名称/doSomething https://localhost:portNumber/applicationName/doSomething"
"https://计算机名称:端口号/应用程序名称/doSomething https://computerName:portNumber/applicationName/doSomething"
"https://ip地址:端口号/应用程序名称/doSomething https://ipAddress:portNumber/applicationName/doSomething"
第二个和第三个请求是为了控制台其他用户计算机的应用程序而发出的。
问题是，如果请求来自本地主机，控制台应用程序在读取传入数据和发送回响应方面不会出现问题。但
如果请求带有计算机名称或 IP 地址，则浏览器会显示认证警告并希望用户单击
“继续访问此网站（不推荐）”链接。
我们考虑通过代码创建三个不同的证书。
但即使使用 sslstream 与其中三个是可能的，我们也不能决定选择真正的认证，因为我们首先进行身份验证，然后接收数据。因此，当我们捕获传入请求时，身份验证必须已经完成。
另一种方法是强制套接字侦听器或 sslstream 将所有这三个请求视为本地主机。因此，对于每一个身份验证都将作为本地主机进行。但我找不到实际的方法。
这是代码。我给出代码是因为 SslStream 的用法可能有一些错误。
