Functions

func IsForwarded

func IsForwarded(header http.Header) bool

IsForwarded returns true if a request contains any x-forwarded header.

func ParseXForwardedFor

func ParseXForwardedFor(header http.Header) iter.Seq2[int, net.IP]

ParseXForwardedFor returns an iterator of all valid IP addresses found in X-Forwarded-For header. It yields IP addresses in reverse order so we can easily find the first mach from the rightmost value.

func ParseXForwardedHost(header http.Header) string

ParseXForwardedHost returns the (trimmed) value of X-Forwarded-Host header.

func ParseXForwardedProto

func ParseXForwardedProto(header http.Header) string
