nginx 0.7.18 *) Change: the "underscores_in_headers" directive; now nginx does not allows underscores in a client request header line names. *) Feature: the ngx_http_secure_link_module. *) Feature: the "real_ip_header" directive supports any header. *) Feature: the "log_subrequest" directive. *) Feature: the $realpath_root variable. *) Feature: the "http_502" and "http_504" parameters of the "proxy_next_upstream" directive. *) Bugfix: the "http_503" parameter of the "proxy_next_upstream" or "fastcgi_next_upstream" directives did not work. *) Bugfix: nginx might send a "Transfer-Encoding: chunked" heaer line for HEAD requests. *) Bugfix: now accept threshold depends on worker_connections.
