Re: which module for this purpose?

By using a PerlAccessHandler, you are adding a step into the standard
apache process.

So:
 - the user goes to: /path/file.xyz
 - your access handler performs its checks
 - Allowed?
  - Y :
    - return OK
    - file served by standard apache means
  - N :
    - return DENY
    - apache sends a 403 (or whatever) response

mhh,I understood for your meanings.but my real question is how I can
send the file to clients after returning OK.here is my apache config
and modperl script,please give more helps.thanks!

from httpd.conf:

PerlModule DLAuth

<Location /flv>
   SetHandler perl-script
   PerlHandler DLAuth
</Location>


my handler:

sub handler {

   my $r = shift;
   my $q = Apache::Request->new($r);

   my $uri = $r->uri;
   my $file = (split/\//,$uri)[-1];

   my $c = $r->connection;
   my $ip = $ENV{'HTTP_X_FORWARDED_FOR'} ?
$ENV{'HTTP_X_FORWARDED_FOR'} : $c->remote_ip;

   return FORBIDDEN unless $ip;

   my $ip_int = unpack('N',inet_aton($ip));

   my $str = $q->param('auth') || '';
   $str = decode_base64($str);

   my ($ip_int2,$time) = split/-/,$str;
   $ip_int2 ||= 0;
   $time ||= 0;

   if ($ip_int != $ip_int2  or time() - $time > EXPIRE * 3600) {
       return FORBIDDEN;
   }else {
       $r->internal_redirect(DLDIR. '/' .$file);
   }

   return OK;
}

=============
How to send the file (given the name is music.mp3) to clients then?
I tried,but didn't get the way to use default apache handler for the
same location of '/flv'.So I used a internal_redirect to another
directory instead.but this is not good,since users can get the real
directory just by guess.

Thanks!
