From source file:business.services.FileService.java

public HttpEntity<InputStreamResource> downloadAccessLog(String filename,
        boolean writeContentDispositionHeader) {

        Path f = fileSystem.getPath(accessLogsPath, filename).normalize();
        // filter path names that point to places outside the logs path.
        // E.g., to prevent that in cases where clients use '../' in the filename
        // arbitrary locations are reachable.
        if (!Files.isSameFile(path, f.getParent())) {
            // Path f is not in the upload path. Maybe 'name' contains '..'?
