36 /**
37  * The Strict HostnameVerifier works the same way as Sun Java 1.4, Sun
38  * Java 5, Sun Java 6-rc.  It's also pretty close to IE6.  This
39  * implementation appears to be compliant with RFC 2818 for dealing with
40  * wildcards.
41  * <p/>
42  * The hostname must match either the first CN, or any of the subject-alts.
43  * A wildcard can occur in the CN, and in any of the subject-alts.  The
44  * one divergence from IE6 is how we only check the first CN.  IE6 allows
45  * a match against any of the CNs present.  We decided to follow in
46  * Sun Java 1.4's footsteps and only check the first CN.  (If you need
47  * to check all the CN's, feel free to write your own implementation!).
48  * <p/>
49  * A wildcard such as "*.foo.com" matches only subdomains in the same
50  * level, for example "a.foo.com".  It does not match deeper subdomains
51  * such as "a.b.foo.com".
