When proxying to a https, It looks like the code should append “SSLProxyEngine on” to the apache config file. From balancer-lib.pl (176):

# If proxying to SSL, turn on SSLProxyEngine
my $ssl = 0;
foreach my $url (@{$balancer->{'urls'}}) {
	$ssl = 1 if ($url =~ /^https:/i);
	}
.....

However, I had to manually enter that line to get this working even though I was proxying to an https url. Is this a bug?
