Multiple domain SSL in IIS7

Is there a way to apply multiple purchased SSL certificates on multiple domains on just one IP address, using IIS7? If not, what is the best alternative? I am thinking to either purchase a second IP address, or maybe change away from IIS7? What are my options here?
Thank you.

Why not? As I know SSL certificates are dedicated to Domain names not IP addresses.
Have you tried Host Header (Host Names in IIS 7)?

I have tried host headers, but from what I figured, that is only good for sub-domains, like site1.mydomain.com, site2.mydomain.com.

I am trying to do domain1.com and domain2.com

If I try to assign the SSL to the domain2.com, then it changes it for domain1.com so they share the same SSL cert, which will not work, as the certs are specific to each domain separately.

Hi There,

Yes/No, SSL support in IIS 7/6 is relatively the same. You will be able to use wildcard SSL for multiple site on a single ip with the condition that all sites are sharing the same root domain.  For example site1.domain.com site2.domain.com testsite.domain.com. The wildcard would be for *.domain.com.

Take a look at this as an example:
http://www.sslshopper.com/article-ssl-host-headers-in-iis-7.html ;

Now if you want site1.domain.com and site2.otherdomain.com, you will need 2 IP Addresses.

cheers,

That is what I thought. Are there alternatives to IIS that I can run on windows server 2008 that would allow 2 separate domains on 1 ip address?

I am sorry to say, No. this is a requirement for SSL. You will need 2 ip addresses.
