Parse multiple certificates in CA chain

[tracend]

CA certs may be many in number, in which case they can be parsed and served as an array of certs, as noted in this article:
http://nodejs.md/blog/https-server-with-multiple-domains-on-same-port-and-instance/

This is the relevant code:

function sslCAdecode(source) {
	var ca		= [];
	if (!source || typeof(source) !== "string")
		return ca;
		ca = source.split(/-----END CERTIFICATE-----[\s\n]+-----BEGIN CERTIFICATE-----/).map(function (v, k, arr) {
			if (k) {
				v = '-----BEGIN CERTIFICATE-----' + v;
			}
			if (k !== arr.length - 1) {
				v = v + '-----END CERTIFICATE-----';
			}
			v = v.replace(/^\n+/,'').replace(/\n+$/,'');
			return v;
		});
	return ca;
};

Use:

creds.ca = sslCAdecode( fs.readFileSync( site.credentials.ca, 'utf8') );
