I have purchase SSL for secure Site from [Verisign](http://www.verisign.com/). I have configured it and its working properly on <https://www.example.com> . I have subdomain app.example.com . i need to work SSL on this domain also. I have 2 Questions. 

1- Will same SSL will work for the `subdomain` too? **[My SSL is not wildcard SSL]**

2- If it will not work. then how can i change the same SSL that it should only work on [app.example.com](http://app.example.com). i mean is there any way to change purchased SSL for subdomain. and How can i do this.

<https://www.example.com> and <http://app.example.com> point to the same IP address `xxx.xxx.xxx.xxx`
