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.
