type Handler struct {
	// How long to wait for the PROXY protocol header to be received.
	// Defaults to zero, which means timeout is disabled.
	Timeout caddy.Duration `json:"timeout,omitempty"`

	// An optional list of CIDR ranges to allow/require PROXY headers from.
	Allow []string `json:"allow,omitempty"`

	// Deny is an optional list of CIDR ranges to
	// deny PROXY headers from.
	Deny []string `json:"deny,omitempty"`

	// FallbackPolicy specifies the policy to use if the downstream
	// IP address is not in the Allow list nor is in the Deny list.
	//
	// NOTE: The generated docs which describe the value of this
	// field is wrong because of how this type unmarshals JSON in a
	// custom way. The field expects a string, not a number.
	//
	// Accepted values are: IGNORE, USE, REJECT, REQUIRE, SKIP
	//
	// - IGNORE: address from PROXY header, but accept connection
	//
	// - USE: address from PROXY header
	//
	// - REJECT: connection when PROXY header is sent
	//   Note: even though the first read on the connection returns an error if
	//   a PROXY header is present, subsequent reads do not. It is the task of
	//   the code using the connection to handle that case properly.
	//
	// - REQUIRE: connection to send PROXY header, reject if not present
	//   Note: even though the first read on the connection returns an error if
	//   a PROXY header is not present, subsequent reads do not. It is the task
	//   of the code using the connection to handle that case properly.
	//
	// - SKIP: accepts a connection without requiring the PROXY header.
	//   Note: an example usage can be found in the SkipProxyHeaderForCIDR
	//   function.
	//
	// Default: IGNORE
	//
	// Policy definitions are here: https://pkg.go.dev/github.com/pires/go-proxyproto#Policy
	FallbackPolicy Policy `json:"fallback_policy,omitempty"`
