annotate src/event/ngx_event_openssl.c @ 547:818fbd4750b9 release-0.2.2
nginx-0.2.2-RELEASE import
*) Feature: the "config errmsg" command of the ngx_http_ssi_module.
*) Change: the ngx_http_geo_module variables can be overridden by the
"set" directive.
*) Feature: the "ssl_protocols" and "ssl_prefer_server_ciphers"
directives of the ngx_http_ssl_module and ngx_imap_ssl_module.
*) Bugfix: the ngx_http_autoindex_module did not show correctly the
long file names;
*) Bugfix: the ngx_http_autoindex_module now do not show the files
starting by dot.
*) Bugfix: if the SSL handshake failed then another connection may be
closed too.
Thanks to Rob Mueller.
*) Bugfix: the export versions of MSIE 5.x could not connect via HTTPS.
