а вот локейшн и обработчик, которые
отвечают за проверку
[code]
location /rcaptcha/ {

rewrite ^ $cookie_fu redirect;
}
rewrite ^ /test.html redirect;
}
perl_set $check_input '
sub {
use String::CRC32;
my $r = shift;
my $input=$r->args;
$input=~ s/.*input=(.+)/$1/g;
my $cookie_ct=$r->header_in("Cookie");
$cookie_ct=~ s/.+ct=([^\ ]+).*/$1/g;
if ( $cookie_ct == crc32($input.$r->remote_addr) ) { return 1; }
else { return 0; }
}';
[/code]
