nginx 0.8.46 *) Change: now the "proxy_no_cache", "fastcgi_no_cache", "uwsgi_no_cache", and "scgi_no_cache" directives affect on a cached response saving only. *) Feature: the "proxy_cache_bypass", "fastcgi_cache_bypass", "uwsgi_cache_bypass", and "scgi_cache_bypass" directives. *) Bugfix: nginx did not free memory in cache keys zones if there was an error during working with backend: the memory was freed only after inactivity time or on memory low condition.
