func ServeContent 

func ServeContent(w http.ResponseWriter, r *http.Request, name string, modtime time.Time, content io.Reader, size int64)

ServeContent replies to the request using the content in the provided Reader. The main benefit of ServeContent over io.Copy is that it handles Range requests properly, sets the MIME type, and handles If-Match, If-Unmodified-Since, If-None-Match, If-Modified-Since, and If-Range requests.

If the response's Content-Type header is not set, ServeContent first tries to deduce the type from name's file extension and, if that fails, falls back to reading the first block of the content and passing it to DetectContentType. The name is otherwise unused; in particular it can be empty and is never sent in the response.

If modtime is not the zero time or Unix epoch, ServeContent includes it in a Last-Modified header in the response. If the request includes an If-Modified-Since header, ServeContent uses modtime to decide whether the content needs to be sent at all.

If the content's Seek method work: ServeContent uses a seek to the end of the content to determine its size, and the param size is ignored. The same as http.ServeFile If the content's Seek method doesn't work: ServeContent uses the param size to generate a onlySizeSeekable as a pseudo io.ReadSeeker. If size < 0, use chunk or connection close instead

If the caller has set w's ETag header formatted per RFC 7232, section 2.3, ServeContent uses it to handle requests using If-Match, If-None-Match, or If-Range.

Note that *os.File implements the io.ReadSeeker interface.

func TransportWithProxyTarget 

func TransportWithProxyTarget(t *http.Transport, fixedProxyUrl string, fixedProxyTarget string) *http.Transport

TransportWithProxyTarget wraps http.RoundTripper with request url replaced by Target resolved by resolver. fixedProxyUrl is proxy's url, like socks5://127.0.0.1:8080 fixedProxyTarget is as like gRPC Naming for proxy service discovery, with Host in TargetUrl replaced if not empty.
