type ChainedServerInfo struct {

	Addr string

	// Cert: optional PEM encoded certificate for the server. If specified,
	// server will be dialed using TLS over tcp. Otherwise, server will be
	// dialed using plain tcp. For OBFS4 proxies, this is the Base64-encoded obfs4
	// certificate.
	Cert string

	// AuthToken: the authtoken to present to the upstream server.
	AuthToken string

	// Trusted: Determines if a host can be trusted with plain HTTP traffic.
	Trusted bool

	// MaxPreconnect: the maximum number of preconnections to keep
	MaxPreconnect int

	// Bias indicates a relative biasing factor for proxy selection purposes.
	// Proxies are bias 0 by default, meaning that they're prioritized by the
	// usual bandwidth and RTT metrics. Proxies with a higher bias are
	// preferred over proxies with a lower bias irrespective of their measured
	// performance.

	// for desktop clients using TLS represented as strings.

	// TLSMobileOrderedCipherSuiteNames: The ordered list of cipher suites to use
	// for mobile clients using TLS represented as strings. This may differ from
	// the ordering for desktop because performance of AES ciphers is more of a
	// concern on mobile.
	TLSMobileOrderedCipherSuiteNames []string

	// TLSServerNameIndicator: Specifies the hostname that should be sent by the
	// client as the Server Name Indication header in a TLS request.  If not
	// provided, the client should not send an SNI header.
	TLSServerNameIndicator string

	// TLSClientSessionCacheSize: the size of client session cache to use. Set to

	TLSClientSessionState string

	// Location: the location where the server resides.
	Location ServerLocation

	// MultipathEndpoint: The host name to which this server eventually
	// connects via multipath. Servers with the same MultipathEndpoint need to
	// be bonded together to form a single dialer. Empty if the server does not
	// support multipath.
