Forgive me if there is something already online describing the following, but I was unable to locate anything specific. I hope I explain it properly.
We have a client with a domain njar.com that also needs an SSL connection. The client would like to use secure.njar.com for the HTTPS connection, but needs it to point to their existing njar.com site. So, if you were to type https://secure.njar.com, it would point to the existing site for http://njar.com. So in the end, https://secure.njar.com and http://njar.com would be the same site. I hope I explained that ok.
