SSL 如何在两个连接的域上工作？
我已阅读相关问题，但找不到我要找的东西。 我已经设置了一个域“domain.com”，并创建了两个子域“client.domain.com”和“client-intern.domain.com”。此外，“client.domain.com/intern”有一个指向“client-intern.domain.com”的重定向活动。
如果我为“client.domain.com”购买单个 SSL 证书，当客户端访问“client.domain.com/intern”时，数据传输是否也会受到保护？ 或者我是否必须为“client-intern.domain.com”购买第二个证书？
预先感谢您的澄清， Paul
更新：如果在 Web 浏览器地址栏中输入“client.domain.com/intern”，则该地址仍保留在那里，并且浏览器仍会显示“client-intern.domain.com”的内容。
I've read through related questions but couldn't quite find what I am looking for.
I have set up a domain just as "domain.com" and created two subdomains "client.domain.com" and "client-intern.domain.com". Further, there is a redirect active for "client.domain.com/intern" pointing to "client-intern.domain.com".
If I buy a single SSL certificate for "client.domain.com", will the data transfer also be secured when the client is going to "client.domain.com/intern"?
Or do I have to purchase a second certificate for "client-intern.domain.com"?
Thanks in advance for clarification,
Paul
UPDATE: If entering "client.domain.com/intern" into the web browsers address bar, this address remains there and the browser shows the content of "client-intern.domain.com" nonetheless.

您需要一个通配符证书来覆盖多个子域（在您的情况下为domain.com、client.domain.com 和client-intern.domain.com）。某些 CA 可能会为您提供一个选项，免费或支付少量额外费用，将一个或两个子域包含到证书中（作为备用名称字段），但这取决于 CA，一般来说，正确的方法是使用通配符证书。您可以在此处（GlobalSign 网站）了解有关通配符证书的信息。
You need a wildcard certificate to cover multiple subdomains (in your case domain.com, client.domain.com and client-intern.domain.com). Some CAs might offer you an option to include one or two subdomains into the certificate (as alternative name field) for free or for a small additional fee, but this is CA-dependent and in general the right way is a wildcard certificate. You can read about wildcard certs here (GlobalSign site).
