Any ideas?

I use $$.$r->uri().$connections.time where $connections is an
incremental
value defined before sub handler {...} and do $connections++ w/in the
handler block (also realizing that you're porting CGI's and
will have to
get the uri elsewhere).
For example:
package foo;
my $connections = 0;
sub handler {
my $r = shift ;
...
...
...
my $unique_id = $$ . $r->uri() . $connections . time ;
...
...
...
$connections++ ;
}
1;
