I'm guessing you already checked your web server configuration for the SSL 
instance of the virtual host. If not, do.

Something I find to be very useful is to add (if it's not already there) 
'require CGI::Carp' to the perl code. Then you can add carp('yourmessage') 
calls wherever you like in order to see what is really going on. The 
messages will show up in the web server's error log (typically 
/var/log/httpd/error_log on many Linux systems.)

Additionally, if you wrap them in a statement like:

	carp("Received name with value = " . $Name) if $Debug;

Then you can enable/disable them with one easy edit by assigning $Debug the 
value of either 0 or 1.
