func FlushingIoCopy ¶

func FlushingIoCopy(dst io.Writer, src io.Reader, buf []byte) (written int64, err error)

FlushingIoCopy is analogous to buffering io.Copy(), but also attempts to flush on each iteration. If dst does not implement http.Flusher(e.g. net.TCPConn), it will do a simple io.CopyBuffer(). Reasoning: http2ResponseWriter will not flush on its own, so we have to do it manually.

func RemoveHopByHop ¶

func RemoveHopByHop(header http.Header)

func StripPort ¶

func StripPort(address string) string

borrowed from `proxy` plugin

func WriteSiteNotFound ¶

func WriteTextResponse ¶

WriteTextResponse writes body with code status to w. The body will be interpreted as plain text.
