annotate 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.
