TLS版本

常见应用： https其实就是建构在SSL/TLS之上的 http协议。

1) setProtocol="TLS" will enable SSLv3 and TLSv1
2) setProtocol="TLSv1.2" will enable SSLv3, TLSv1, TLSv1.1 and TLS v1.2
3) setProtocol="TLSv1.1" will enable SSLv3, TLSv1, and TLSv1.1
4) setProtocol="TLSv1" will enable SSLv3 and TLSv1
5) setProtocol="SSL" will enable SSLv3 and TLSv1
6) setProtocol="SSLv3" will enable SSLv3 and TLSv1
7) setProtocol="SSLv2" won‘t work
