Added clearing of r->valid_unparsed_uri on internal redirects.
This resolves issue with try_files (see ticket #70), configuration like
location / { try_files $uri /index.php; }
location /index.php { proxy_pass http://backend; }
caused nginx to use original request uri in a request to a backend.
Historically, not clearing of the r->valid_unparsed_uri on internal redirect
was a feature: it allowed to pass the same request to (another) upstream
server via error_page redirection. Since then named locations appeared
though, and it's time to start resetting r->valid_unparsed_uri on internal
redirects. Configurations still using this feature should be converted
to use named locations instead.
Patch by Lanshun Zhou.

The .Nm is known for its high performance, stability, rich feature set, simple configuration, and low resource consumption. .Pp The options are as follows: .Bl -tag -width ".Fl d Ar directives" .It Fl ?\& | h Print help. .It Fl c Ar file Use an alternative configuration .Ar file . .It Fl g Ar directives Set global configuration directives. See .Sx EXAMPLES for details. .It Fl p Ar prefix Set prefix path. Default value is .Pa %%PREFIX%% . .It Fl q Suppress non-error messages during configuration testing. .It Fl s Ar signal Send signal to the master process. The argument .Ar signal can be one of: .Cm stop , quit , reopen , reload . The following table shows the corresponding system signals. .Pp .Bl -tag -width ".It Cm reopen" -compact .It Cm stop .Dv SIGTERM .It Cm quit .Dv SIGQUIT .It Cm reopen .Dv SIGUSR1 .It Cm reload .Dv SIGHUP .El .It Fl t Don't run, just test the configuration file. The .Nm checks configuration for correct syntax and then tries to open files referred in configuration. .It Fl v Print .Nm version. .It Fl V Print .Nm version, compiler version and .Pa configure script parameters. .El .Sh SIGNALS The master process of .Nm can handle the following signals. .Pp .Bl -tag -width ".It Dv SIGINT , SIGTERM" -compact .It Dv SIGINT , SIGTERM Shut down quickly. .It Dv SIGHUP Reload configuration, start the new worker process with a new configuration, gracefully shut down old worker processes. .It Dv SIGQUIT Shut down gracefully. .It Dv SIGUSR1 Reopen log files. .It Dv SIGUSR2 Upgrade .Nm executable on the fly. .It Dv SIGWINCH Shut down gracefully worker processes. .El .Pp While there's no need to explicitly control worker processes normally, they support some signals, too: .Pp .Bl -tag -width ".It Dv SIGINT , SIGTERM" -compact .It Dv SIGTERM Shut down quickly. .It Dv SIGQUIT Shut down gracefully. .It Dv SIGUSR1 Reopen log files. .El .Sh DEBUGGING LOG To enable a debugging log, reconfigure .Nm to build with debugging: .Pp .Dl "./configure --with-debug ..." .Pp and then set the .Cm debug level of the .Va error_log : .Pp .Dl "error_log /path/to/log debug;" .Pp It is also possible to enable the debugging for some IP address: .Bd -literal -offset indent events { debug_connection 127.0.0.1; } .Ed .Sh FILES .Bl -tag -width indent -compact .It Pa %%PID_PATH%% Contains the process ID of the .Nm listening for connections. The content of this file is not sensitive; it can be world-readable. .It Pa %%CONF_PATH%% Main configuration file. .It Pa %%ERROR_LOG_PATH%% Error log file. .El .Sh EXIT STATUS Exit status is 0 on success, or 1 if the command fails. .Sh EXAMPLES .Bd -literal nginx -t -c ~/mynginx.conf -g "pid /var/run/mynginx.pid; worker_processes 2;" .Ed Test configuration file .Pa ~/mynginx.conf with global directives for PID and quantity of worker processes. .Sh SEE ALSO .\"Xr nginx.conf 5 .\"Pp Documentation at .Pa http://nginx.org/ and .Pa http://sysoev.ru/nginx/ . .Pp For questions and technical support, please refer to .Pa http://nginx.org/en/support.html . .Sh HISTORY Development of .Nm started in 2002, with the first public release on October 4, 2004. .Sh AUTHORS .An -nosplit .An Igor Sysoev Aq igor@sysoev.ru .Pp This manual page was written by .An Sergey A. Osokin Aq osa@FreeBSD.org.ru as a result of compilation of many .Nm documents all over the world.
