2017-04-11Added support for the "308 Permanent Redirect" (ticket #877).Simon Leblanc1-2/+12
2017-03-24Added support for "429 Too Many Requests" response (RFC6585).Piotr Sikora1-2/+18
This change adds reason phrase in status line and pretty response body when "429" status code is used in "return", "limit_conn_status" and/or "limit_req_status" directives. Signed-off-by: Piotr Sikora <piotrsikora@google.com>
2017-01-31Implemented the "server_tokens build" option.Ruslan Ermilov1-1/+12
Based on a patch by Tom Thorogood.
2016-11-04Style: switch.Ruslan Ermilov1-1/+0
2016-10-03Do not set last_buf flag in subrequests.Roman Arutyunyan1-1/+1
The last_buf flag should only be set in the last buffer of the main request. Otherwise, several last_buf flags can appear in output. This can, for example, break the chunked filter, which will include several final chunks in output.
2016-05-20HTTP/2: the "421 Misdirected Request" response (closes #848).Valentin Bartenev1-1/+14
Since 4fbef397c753 nginx rejects with the 400 error any attempts of requesting different host over the same connection, if the relevant virtual server requires verification of a client certificate. While requesting hosts other than negotiated isn't something legal in HTTP/1.x, the HTTP/2 specification explicitly permits such requests for connection reuse and has introduced a special response code 421. According to RFC 7540 Section 9.1.2 this code can be sent by a server that is not configured to produce responses for the combination of scheme and authority that are included in the request URI. And the client may retry the request over a different connection. Now this code is used for requests that aren't authorized in current connection. After receiving the 421 response a client will be able to open a new connection, provide the required certificate and retry the request. Unfortunately, not all clients currently are able to handle it well. Notably Chrome just shows an error, while at least the latest version of Firefox retries the request over a new connection.

2016-03-22Reconsidered server_tokens with an empty value.Ruslan Ermilov1-12/+3
An empty value will be treated as "off".
2016-03-15Added variables support to server_tokens.Ruslan Ermilov1-15/+43
It can now be set to "off" conditionally, e.g. using the map directive. An empty value will disable the emission of the Server: header and the signature in error messages generated by nginx. Any other value is treated as "on", meaning that full nginx version is emitted in the Server: header and error messages generated by nginx.

2012-11-26Request body: improved handling of incorrect chunked request body.Maxim Dounin1-1/+1
While discarding chunked request body in some cases after detecting request body corruption no error was returned, while it was possible to correctly return 400 Bad Request. If error is detected too late, make sure to properly close connection. Additionally, in ngx_http_special_response_handler() don't return body of 500 Internal Server Error to a client if ngx_http_discard_request_body() fails, but disable keepalive and continue.
2012-11-21Request body: fixed "501 Not Implemented" error handling.Maxim Dounin1-2/+3
It is not about "Method" but a generic message, and is expected to be used e.g. if specified Transfer-Encoding is not supported. Fixed message to match RFC 2616. Additionally, disable keepalive on such errors as we won't be able to read request body correctly if we don't understand Transfer-Encoding used.

2011-10-12Clear old Location header (if any) while adding a new one.Maxim Dounin1-0/+2
This prevents incorrect behaviour when another redirect is issued within error_page 302 handler.

2011-09-27Fix for incorrect 201 replies from dav module.Maxim Dounin1-3/+2
Replies with 201 code contain body, and we should clearly indicate it's empty if it's empty. Before 0.8.32 chunked was explicitly disabled for 201 replies and as a result empty body was indicated by connection close (not perfect, but worked). Since 0.8.32 chunked is enabled, and this causes incorrect responses from dav module when HTTP/1.1 is used: with "Transfer-Encoding: chunked" but no chunks at all. Fix is to actually return empty body in special response handler instead of abusing r->header_only flag. See here for initial report: http://mailman.nginx.org/pipermail/nginx-ru/2010-October/037535.html
