nginx 0.7.45 *) Change: now the "proxy_cache" and the "proxy_cache_valid" can be set on different levels. *) Change: the "clean_time" parameter of the "proxy_cache_path" directive is canceled. *) Feature: the "max_size" parameter of the "proxy_cache_path" directive. *) Feature: the ngx_http_fastcgi_module preliminary cache support. *) Feature: now on shared memory allocation errors directive and zone names are logged. *) Bugfix: the directive "add_header last-modified ''" did not delete a "Last-Modified" response header line; the bug had appeared in 0.7.44. *) Bugfix: a relative path in the "auth_basic_user_file" directive given without variables did not work; the bug had appeared in 0.7.44.
