advance that the response will not be cached (e.g., when using
proxy_cache_min_uses).

backend with caching disabled; the new directives
"proxy_cache_lock_age", "fastcgi_cache_lock_age",
"scgi_cache_lock_age", and "uwsgi_cache_lock_age" specify a time
after which the lock will be released and another attempt to cache a

FastCGI request to the next upstream server.
*) Bugfix: in logging to syslog.
Changes with nginx 1.7.5 16 Sep 2014
*) Security: it was possible to reuse SSL sessions in unrelated contexts
if a shared SSL session cache or the same TLS session ticket key was
used for multiple "server" blocks (CVE-2014-3616).

nginx (pronounced "engine X") is a lightweight web (HTTP) server/reverse proxy
and mail (IMAP/POP3) proxy written by Igor Sysoev.
nginx has been running for more than three years on many heavily loaded Russian
sites including Rambler (RamblerMedia.com). In March 2007 about 20% of all
Russian virtual hosts were served or proxied by nginx. According to Google
Online Security Blog nginx serves or proxies about 4% of all Internet virtual
hosts, although Netcraft shows much less percent.
