func AppendForwardedForHeader

func AppendForwardedForHeader(req *http.Request)

    Prepares the X-Forwarded-For header for another forwarding hop by appending the previous sender's IP address to the X-Forwarded-For chain.

    func ChooseBindAddress

    func ChooseBindAddress(bindAddress net.IP) (net.IP, error)

      If bind-address is usable, return it directly If bind-address is not usable (unset,, or loopback), we will use the host's default interface.

      func ChooseHostInterface

      func ChooseHostInterface() (net.IP, error)

        ChooseHostInterface is a method used fetch an IP for a daemon. If there is no routing info file, it will choose a global IP from the system interfaces. Otherwise, it will use IPv4 and IPv6 route information to return the IP of the interface with a gateway on it (with priority given to IPv4). For a node with no internet connection, it returns error.

        func CloneHeader

        func CloneHeader(in http.Header) http.Header

          CloneHeader creates a deep copy of an http.Header.

          func CloneRequest

          func CloneRequest(req *http.Request) *http.Request

            CloneRequest creates a shallow copy of the request along with a deep copy of the Headers.

              ConnectWithRedirects uses dialer to send req, following up to 10 redirects (relative to originalLocation). It returns the opened net.Conn and the raw response bytes. If requireSameHostRedirects is true, only redirects to the same host are permitted.

              func FormatURL

              func FormatURL(scheme string, host string, port int, path string) *url.URL

              func GetClientIP

              func GetClientIP(req *http.Request) net.IP

                Extracts and returns the clients IP from the given request. Looks at X-Forwarded-For header, X-Real-Ip header and request.RemoteAddr in that order. Returns nil if none of them are set or is set to an invalid value.

                      func IsProbableEOF(err error) bool

                        IsProbableEOF returns true if the given error resembles a connection termination scenario that would justify assuming that the watch is empty. These errors are what the Go http stack returns back to us which are general connection closure errors (strongly correlated) and callers that need to differentiate probable errors in connection behavior between normal "this is disconnected" should use the method.
