code: func (ctx *RequestCtx) RedirectBytes(uri []byte, statusCode int) {
  	s := b2s(uri)
  	ctx.Redirect(s, statusCode)
  }
docs: // RedirectBytes sets 'Location: uri' response header and sets
  // the given statusCode.
  //
  // statusCode must have one of the following values:
  //
  //    * StatusMovedPermanently (301)
  //    * StatusFound (302)
  //    * StatusSeeOther (303)
  //    * StatusTemporaryRedirect (307)
  //    * StatusPermanentRedirect (308)
  //
  // All other statusCode values are replaced by StatusFound (302).
  //
  // The redirect uri may be either absolute or relative to the current
  // request uri. Fasthttp will always send an absolute uri back to the client.
  // To send a relative uri you can use the following code:
  //
  //   strLocation = []byte("Location") // Put this with your top level var () declarations.
  //   ctx.Response.Header.SetCanonical(strLocation, "/relative?uri")
  //   ctx.Response.SetStatusCode(fasthttp.StatusMovedPermanently)
  //
