public interface HostnameVerifier
During handshaking, if the URL's hostname and the server's identification hostname mismatch, the verification mechanism can call back to implementers of this interface to determine if this connection should be allowed.
The policies can be certificate-based or may depend on other authentication schemes.
These callbacks are used when the default rules for URL hostname verification fail.
verifyVerify that the host name is an acceptable match with the server's authentication scheme.
hostname- the host name
session- SSLSession used on the connection to host
- true if the host name is acceptable
