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.


http://perl.apache.org/docs/2.0/api/Apache2/Log.html#LogLevel_Methods

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?

RE: Printing for debugging

[Raful Mr Mitchell H]

Thanks!  Using the Apache2::RequestUtil and Apache2::Log, I can find out what 
my variables' values are to debug and check my code.
