RE: Printing for debugging

["Raful Mr Mitchell H" <suppressed>]

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

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?
