3) that has helped. I've ended up with

        my $slog = $c->base_server()->log();
        $slog->warn('served socket policy to: ', $c->remote_ip(), ',
bytes: ', $nbytes);

   - I had to take warn() because don't want to increase LogLevel.
  But actually I would prefer printing to access_log and not error_log.
  Is there a way for that?

2) I've looked at
http://svn.apache.org/viewvc/apr/apr/trunk/network_io/unix/sendrecv.c?view=markup
  If APR::Socket::send() is autogenerated from apr_socket_send()
  then the loop is already there and I don't need it in my Perl code.

Alex

PS: My current code:

package SocketPolicy;

# Run: semanage port -a -t http_port_t -p tcp 843
# And add following lines to the httpd.conf
# Listen 843
# <VirtualHost _default_:843>
#       PerlModule                   SocketPolicy
#       PerlProcessConnectionHandler SocketPolicy
# </VirtualHost>

use strict;
use warnings FATAL => 'all';

use Apache2::Connection();
use APR::Socket();
use Apache2::ServerRec();

use Apache2::Const(-compile => 'OK');
use APR::Const(-compile => 'SO_NONBLOCK');

use constant POLICY =>
qq{<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM
"http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">

<cross-domain-policy>
<allow-access-from domain="*" to-ports="8080"/>
</cross-domain-policy>
\0};

sub handler {
        my $c = shift;
        my $sock = $c->client_socket;

        # set the socket to the blocking mode
        $sock->opt_set(APR::Const::SO_NONBLOCK => 0);

        my $nbytes = $sock->send(POLICY);

        my $slog = $c->base_server()->log();
        $slog->warn('served socket policy to: ', $c->remote_ip(), ',
bytes: ', $nbytes);

        Apache2::Const::OK;
}
