IIS, HTTPS and multiple domains within one website

We're running IIS 7.

We have a Joomla installation where 3 domains are served from one website in IIS. The code at the root determines the domain entered by the user and forwards accordingly.

The problem comes now in my trying to bind https to our 3 domains in IIS.

IIS seems to not want me to assign multiple SSL certificates on the same IP address/website.

I have multiple IP addresses on the server, but don't know if I have to somehow link each with a specific domain (is this necessary and done in DNS?)

So, I'm a bit over my head here and looking for someone to point me towards a solution.

Thanks in advance!

Since you indicate"multiple"certificates, your solution is to bind a different ip for each site.

IIS would do this on a single ip with as San certificate but you need different ips for each binding in your scenario.

This should be possible with a single SSL certificate with SAN (Subject Alternative Names) configured for your different domains.

Free Tool: ZipGrep

ZipGrep is a utility that can list and search zip (.war, .ear, .jar, etc) archives for text patterns, without the need to extract the archive's contents.

Here is a good link, scroll to the section that says adding bindings.
