Will SSL work with multilevel wildcards?

Problem

Will SSL work with multilevel wildcards?

Solution

With the distribution of Firefox 3.5, all major browsers allow only a single level of subdomain matching with certificate names that contain wildcards, in conformance with RFC 2818.

In other words the certificate *.mydomain.com will work for one.mydomain.com or two.mydomain.com but NOT one.two.mydomain.com.
