code: public static String pingHttpsEndpoint(String url, String truststorePath, String truststorePassword, String privateKeyPassword) {
  		return OK_PREFIX;		
  	}
docs: Verify access to a HTTPS endpoint by performing a HTTP-get operation and assures that a proper http-return code (e.g. 200) is returned.
  NOTE: This method is aimed for external http-endpoionts and not internal http-endpoints, e.g. servlet-endpoints.
  
  TODO: What return codes should be handled as ok here? Simpl 2xx codes or som other codes as well?
  TODO: Needs to be implemented...
