Multiple websites sharing ssl port 443

Ok.
Suppose I have site nº 1 with host header "www1.mydomain.com"
and site nº 2 with host header "www2.mydomain.com"

Can I have a wilcard certificate for *.mydomain.com?
Where should I install it?

Thanks!

You can use whatever certificate you want. As long as the client will
recognize that certificate as valid for its intended host.

You install the SSL Certificate for each website that communicates
over SSL. There is nothing special here. It's just how SSL works.

In your example, you can have a single wildcard certificate for
*.mydomain.com and install it in IIS website definition(s) for
www1.mydomain.com and www2.mydomain.com.

Or you can use a single certificate valid for www1.mydomain.com and
www2.mydomain.com. Or any other certificate that will be valid for the
host that it is supposed to represent.
