nginx-0.1.29-RELEASE import *) Feature: the ngx_http_ssi_module supports "include virtual" command. *) Feature: the ngx_http_ssi_module supports the condition command like 'if expr="$NAME"' and "else" and "endif" commands. Only one nested level is supported. *) Feature: the ngx_http_ssi_module supports the DATE_LOCAL and DATE_GMT variables and "config timefmt" command. *) Feature: the "ssi_ignore_recycled_buffers" directive. *) Bugfix: the "echo" command did not show the default value for the empty QUERY_STRING variable. *) Change: the ngx_http_proxy_module was rewritten. *) Feature: the "proxy_redirect", "proxy_pass_request_headers", "proxy_pass_request_body", and "proxy_method" directives. *) Feature: the "proxy_set_header" directive. The "proxy_x_var" was canceled and must be replaced with the proxy_set_header directive. *) Change: the "proxy_preserve_host" is canceled and must be replaced with the "proxy_set_header Host $host" and the "proxy_redirect off" directives, the "proxy_set_header Host $host:$proxy_port" directive and the appropriate proxy_redirect directives. *) Change: the "proxy_set_x_real_ip" is canceled and must be replaced with the "proxy_set_header X-Real-IP $remote_addr" directive. *) Change: the "proxy_add_x_forwarded_for" is canceled and must be replaced with the "proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for" directive. *) Change: the "proxy_set_x_url" is canceled and must be replaced with the "proxy_set_header X-URL http://$host:$server_port$request_uri" directive. *) Feature: the "fastcgi_param" directive. *) Change: the "fastcgi_root", "fastcgi_set_var" and "fastcgi_params" directive are canceled and must be replaced with the fastcgi_param directives. *) Feature: the "index" directive can use the variables. *) Feature: the "index" directive can be used at http and server levels. *) Change: the last index only in the "index" directive can be absolute. *) Feature: the "rewrite" directive can use the variables. *) Feature: the "internal" directive. *) Feature: the CONTENT_LENGTH, CONTENT_TYPE, REMOTE_PORT, SERVER_ADDR, SERVER_PORT, SERVER_PROTOCOL, DOCUMENT_ROOT, SERVER_NAME, REQUEST_METHOD, REQUEST_URI, and REMOTE_USER variables. *) Change: nginx now passes the invalid lines in a client request headers or a backend response header. *) Bugfix: if the backend did not transfer response for a long time and the "send_timeout" was less than "proxy_read_timeout", then nginx returned the 408 response. *) Bugfix: the segmentation fault was occurred if the backend sent an invalid line in response header; the bug had appeared in 0.1.26. *) Bugfix: the segmentation fault may occurred in FastCGI fault tolerance configuration. *) Bugfix: the "expires" directive did not remove the previous "Expires" and "Cache-Control" headers. *) Bugfix: nginx did not take into account trailing dot in "Host" header line. *) Bugfix: the ngx_http_auth_module did not work under Linux. *) Bugfix: the rewrite directive worked incorrectly, if the arguments were in a request. *) Bugfix: nginx could not be built on MacOS X.
