annotate src/event/ngx_event_openssl.c @ 591:8c0cdd81580e release-0.3.17
nginx-0.3.17-RELEASE import
*) Change: now on Linux configure checks the presence of epoll and
sendfile64() in kernel.
*) Feature: the "map" directive supports domain names in the
".domain.tld" form.
*) Bugfix: the timeouts were not used in SSL handshake; the bug had
appeared in 0.2.4.
*) Bugfix: in the HTTPS protocol in the "proxy_pass" directive.
*) Bugfix: when the HTTPS protocol was used in the "proxy_pass"
directive the port 80 was used by default.
