### Return the error { #return-the-error }

After detecting that the credentials are incorrect, return an `HTTPException` with a status code 401 (the same returned when no credentials are provided) and add the header `WWW-Authenticate` to make the browser show the login prompt again:

func reliableRename(srcFilePath, dstFilePath, baseDir string) (err error) {
	if err = reliableMkdirAll(path.Dir(dstFilePath), 0o777, baseDir); err != nil {
		return err
	}

	i := 0
	for {
		// After a successful parent directory create attempt a renameAll.
		if err = Rename(srcFilePath, dstFilePath); err != nil {
			// Retry only for the first retryable error.
			if osIsNotExist(err) && i == 0 {
				i++
				continue

issue if there is one) requesting the feature and describing specific use cases
for it.

If we decide to pursue a feature request, it will go through a thorough process
of API design and review. Any code should come after this.
