I wanted to use IIS 7.5 to host multiple sites under https. The only way I found so far is to have multiple IP addresses link to one server or configure multiple IP addresses on the server and use the IIS site bindings to listen to these alternate IP addresses.
First of we need to configure our network card and add the new IP address to it. Go to the properties of your network card and select IPv4, then click properties.
Next click on Advanced.
Click Add. Then enter the IP address and the subnet mask and press Add.
A second IP address should now be visible in the list. Start IIS manager and right click on your site. Then click Edit Binding.
Select https, select your IP address and select the corresponding certificate.
