*) Feature: the "use_temp_path" parameter of the "proxy_cache_path", "fastcgi_cache_path", "scgi_cache_path", and "uwsgi_cache_path" directives.
*) Feature: the $upstream_header_time variable.
*) Workaround: now on disk overflow nginx tries to write error logs once a second only.
*) Bugfix: the "try_files" directive did not ignore normal files while testing directories. Thanks to Damien Tournoud.
