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.
