2013-02-27Correctly handle multiple X-Forwarded-For headers (ticket #106).Ruslan Ermilov1-3/+3
2013-02-27Fixed separator in $sent_http_cache_control.Ruslan Ermilov1-6/+27
In case multiple "Cache-Control" headers are sent to a client, multiple values in $sent_http_cache_control were incorrectly split by a semicolon. Now they are split by a comma.
2013-02-18Proxy: support for connection upgrade (101 Switching Protocols).Maxim Dounin1-1/+5
This allows to proxy WebSockets by using configuration like this: location /chat/ { proxy_pass http://backend; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; } Connection upgrade is allowed as long as it was requested by a client via the Upgrade request header.
2013-01-21Variables $pipe, $request_length, $time_iso8601, and $time_local.Ruslan Ermilov1-0/+102
Log module counterparts are preserved for efficiency. Based on patch by Kiril Kalchev.
2012-12-17Added checks that disallow adding a variable with an empty name.Ruslan Ermilov1-0/+12
Added variable name syntax checks to "geo" and "map" directives.
2012-11-21Request body: $content_length variable to honor real body size.Maxim Dounin1-2/+37
This allows to handle requests with chunked body by fastcgi and uwsgi modules, and also simplifies handling of various request body modifications.
2012-11-21Request body: $request_body variable generalization.Maxim Dounin1-5/+13
The $request_body variable was assuming there can't be more than two buffers. While this is currently true due to request body reading implementation details, this is not a good thing to depend on and may change in the future.
2012-11-16Variables $request_time and $msec.Ruslan Ermilov1-0/+63
Log module counterparts are preserved for efficiency.
2012-10-29Variables $connection and $connection_requests.Maxim Dounin1-0/+53
Log module counterparts are removed as they aren't used often and there is no need to preserve them for efficiency.
2012-10-03Variable $bytes_sent.Maxim Dounin1-0/+26
It replicates variable $bytes_sent as previously available in log module only. Patch by Benjamin Grössing (with minor changes).
2012-06-21Fixed compile-time conditionals used to detect if X-Forwarded-For supportRuslan Ermilov1-1/+1
is needed.
2012-06-18Style fix.Andrey Belov1-1/+1
2012-06-18New core variable: $status.Andrey Belov1-0/+39
Contains response status code as a 3-digit integer (with leading zeroes if necessary), or one of the following values: 000 - response status code has not yet been assigned 009 - HTTP/0.9 request is being processed
2012-05-17Fixed core variables dynamic access after reconfiguration.Maxim Dounin1-2/+9
If variable was indexed in previous configuration but not in current one, the NGX_HTTP_VAR_INDEXED flag was left set and confused ngx_http_get_variable(). Patch by Yichun Zhang (agentzh), slightly modified.
2012-04-03Fixed spelling in multiline C comments.Ruslan Ermilov1-1/+1
2012-03-27Fixed unconditional MAX_PATH usage (ticket #22).Maxim Dounin1-2/+20
POSIX doesn't require it to be defined, and Debian GNU/Hurd doesn't define it. Note that if there is no MAX_PATH defined we have to use realpath() with NULL argument and free() the result.
2012-03-16Implemented $tcpinfo_rtt, $tcpinfo_rttvar, $tcpinfo_snd_cwnd, andRuslan Ermilov1-0/+73
$tcpinfo_rcv_space variables. Supported on Linux and FreeBSD.
2012-03-15Slight optimization in ngx_http_get_variable_index().Ruslan Ermilov1-1/+1
2012-02-13Variables: honor no_cacheable for not_found variables.Maxim Dounin1-1/+1
Variables with the "not_found" flag set follow the same rules as ones with the "valid" flag set. Make sure ngx_http_get_flushed_variable() will flush non-cacheable variables with the "not_found" flag set. This fixes at least one known problem with $args not available in a subrequest (with args) when there were no args in the main request and $args variable was queried in the main request (reported by Laurence Rowe aka elro on irc). Also this eliminates unneeded call to ngx_http_get_indexed_variable() in cacheable case (as it will return cached value anyway).
2012-01-18Copyright updated.Maxim Konovalov1-0/+1
2011-12-09Fixed: some of $sent_http_* variables may contain header entries that actuallyValentin Bartenev1-12/+29
haven't been sent to a client. The ngx_http_variable_headers() and ngx_http_variable_unknown_header() functions did not ignore response header entries with zero "hash" field. Thanks to Yichun Zhang (agentzh).
