this has been explained many times, you can only read POST data once.
if you need to read it more than once, you need to save it somewhere.
a transparent way to do this is to switch the request method from POST to
GET and store the post data in the query string:

package Apache::POST2GET;

use Apache::Constants qw(M_GET);

sub handler {
    my $r = shift;
    if ($r->method eq 'POST') { 
       my $content = $r->content;
       $r->args($content);
       $r->method('GET');
       $r->method_number(M_GET);
       $r->headers_in->unset('Content-length');
    }
}
