2013-05-02PCRE: retain input pattern for all regular expressions.Piotr Sikora1-1/+1
Previously, input pattern was kept only for regular expressions with named captures, which resulted in error log entries without input pattern for PCRE errors that occured while processing regular expressions without them. Signed-off-by: Piotr Sikora <piotr@cloudflare.com>
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).
