I'm not entirely sure where, in those lines of unindented HTML, you're 
trying to perform your logging.  The only thing I could find quickly was 
the following code, but I can't be certain that's the subject of your 
question.

if( $arp_session->{ErrorNum} ){ print "Got $arp_session->{ErrorStr} for 
$router\n"; }

In order to print log messages to Apache's (or your virtual host's) 
error log, you can use the following.

use Apache2::RequestUtil;
use Apache2::Log;

Apache2::RequestUtil->request->log->error('some_text');

Substituting other log levels (debug, info, warn, etc.) works, as well. 
 See the following URL for more information.

If this isn't what you're seeking, perhaps you could include a more 
concise test case and a more elaborate explanation in your next post?
