Ooops, further checking with collegues showed:

IE *doesn't* display the pages on https://www-test.whaver.com
but Netscape (4.6) does pop up a box as I said.

Interestingly, IE doesn't complain, it just shows a blank page.

I suspect that anybody who charges by the cert is not going to want to issue
you a wildcard cert instead of multiples.

The hostname->subject common name check isn't optional (or shouldn't
be and doesn't appear to be on NS and IE5), but both browsers
support the use of a '*' wildcard to allow matching multiple
machines in a single domain.

So a certificate issued to *.example.com would pass the name
check for www.example.com, test.example.com, and rogue.example.com.
The version 4 browsers (I haven't tried this lately) would
allow the * to be used to mask out larger namespaces (e.g.,
*.com). I don't remember, but it seems that one or more
browsers allowed a common name of '*' to match any domain name.

In practice, the rogue use of this feature (e.g., getting a
cert issued to '*' rather than '*.example.com') is supposed to
be prevented by diligent Certification Authorities.  Are all
the issuing CAs under these 107 trusted root CAs that ship
with IE5 applying this diligence? Your guess is as good as mine.
