Consider an IIS6 installation with multiple Web Sites. Each is intended to be a different subdomain with its own cert (not a wildcard cert). Each has their host-header specified properly.
foo.example.com- port 443. Require SSL w/128 bit. Working properly! It presents its SSL cert properly to the browser. Configured for a specific IP address.
bar.example.com- port 443. Require SSL w/128 bit. Configured for all unassigned addresses. When inspecting the IIS property page, it fully shows the cert for
bar.example.comon the View Certificate button. This is a NEW web site that is having cert problems. It's presenting the cert for foo.example.com. Ouch!
Question: can you have more than one subdomains both running on separate websites with SSL certs on the same port (443)? How would you configure 2 web sites on the same range of 'all unassigned' for the same port (443) ?
Update: ignoring the cert error, when browsing to
https://bar, the content served is from
When NOT using SSL, browsing to
http://bar serves the correct content from
Just one address is assigned to this DMZ server.
