Basically I have a url/link to a text file online and I am trying to download it locally. For some reason, the text file that gets created/downloaded is blank. Open to any suggestions. Thanks!

    def downloadFile(token: String, fileToDownload: String) {

    val url = new URL("http://randomwebsite.com/docs?t=" + token + "&p=tsr%2F" + fileToDownload)
    val connection = url.openConnection().asInstanceOf[HttpURLConnection]
    connection.setRequestMethod("GET")
    val in: InputStream = connection.getInputStream
