Creating CSR with multiple common names in a single CSR

 Hi.  We are configuring SSL for which we were in the process of generating CSR from Oracle HTTP server. But we want to use multiple URL's for a server. 

For example: domain.example.com will be our primary URL and domain2.example. com would be our secondary URL.  I have 3 questions regarding SSL:

1. Can we mention multiple Common Names (CN) in a single CSR?

2. While generating the certificate, can we mention our primary URL in the CN field and secondary URL in the SAN field?

3. If we can we mention the secondary URL in SAN, will it create a Certificate import error when we import the generated certificate in OHS?
