diff src/event/ngx_event_openssl.c @ 4400:a0505851e70c

Added support for TLSv1.1, TLSv1.2 in ssl_protocols directive. Support for TLSv1.1 and TLSv1.2 protocols was introduced in OpenSSL 1.0.1 (-beta1 was recently released). This change makes it possible to disable these protocols and/or enable them without other protocols.
