I cannot see any obvious reason for "getting a blank page", at least not
without seeing some code. Anyway, you will fix it in no time thinking
about "dhandlers" as "fall back components". So, your "execution path"
for "/45" would be:
/autohandler -> /dhandler
For handling the "45" argument, you could use a variation upon
"$m->dhandler_arg" (or "$r->uri" if your prefer).
Remember to not blindly forward such requests. Validate them, croaking
some error on failure.
Here's a dummy dhandler example:
<%init>
# does the request look like "/[ID]"?
if ($m->dhandler_arg =~ /^(\d+)/) {
# ("your_id_handler" should handle "invalid ID" errors)
return $m->comp('your_id_handler', %ARGS, id => $1);
}
# call 911 or something
$m->auto_send_headers(0);
$m->clear_buffer;
$r->status(404);
$r->content_type('text/plain');
$r->send_http_header;
$m->print('Are you lost?');
$m->abort;
</%init>
