The Strict HostnameVerifier works the same way as Sun Java 1.4, Sun
Java 5, Sun Java 6.  It's also pretty close to IE6.  This implementation
appears to be compliant with RFC 2818 for dealing with wildcards.

The hostname must match either the first CN, or any of the subject-alts.
A wildcard can occur in the CN, and in any of the subject-alts.  The
one divergence from IE6 is how we only check the first CN.  IE6 allows
a match against any of the CNs present.  We decided to follow in
Sun Java 1.4's footsteps and only check the first CN.  (If you need
to check all the CN's, feel free to write your own implementation!).


A wildcard such as "*.foo.com" matches only subdomains in the same
level, for example "a.foo.com".  It does not match deeper subdomains
such as "a.b.foo.com".
