Hi,
I'm getting an unknown directive "perl_set" error - I have in my configuration file :

user www-data;
worker_processes 1;

error_log /var/log/nginx/error.log;
pid /var/run/nginx.pid;

events {
worker_connections 1024;
# multi_accept on;
}

http {
include /etc/nginx/mime.types;

access_log /var/log/nginx/access.log;

sendfile on;
#tcp_nopush on;

#keepalive_timeout 0;
keepalive_timeout 65;
tcp_nodelay on;

gzip on;
gzip_disable "MSIE [1-6]\.(?!.*SV1)";

perl_set $client_ip '
sub {
my $r = shift;
my $xff = $r->header_in("x-forwarded-for");
if (!$xff) {
return $r->remote_addr;
} else {
if ($xff =~ /([0-9\.]+).*/) {
return $1;
} else {
return $xff;
}
}
}
';

# create a zone called tellapart_one, able to hold 320K IP addresses.
limit_zone tellapart_one $binary_remote_addr 20m;

# create zone called tellapart_two, with 320 IP addresses,
# such that rate of requests is at most 1 per s.
limit_req_zone $binary_remote_addr zone=tellapart_two:20m rate=10r/s;

include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
}

Can someone tell me what I am doing wrong? I downloaded nginx 0.76 and confgured it with the perl module.

Thanks,
