kan man sætte timeout på en HttpUrlConnection

Kan man sætte timeout på en Url connection ??
Mit problem er, at
"c = (HttpURLConnection) pollUrl.openConnection();"
nogle gange hænger, dvs at der returneres ikke nogen responsecode ??
Tråden står bare og venter.....







    private String myStartSession() throws IOException {
      String cookie = null;
      String pollUrlStr = "http://" + HOST_NAME + "/" + POLL_URL;
      URL pollUrl = new URL(pollUrlStr);
      HttpURLConnection c = null;
    try {
        c = (HttpURLConnection) pollUrl.openConnection();
        logger.debug("OpenConnection, Responscode: " +c.getResponseCode());
        if (c.getResponseCode() == HttpURLConnection.HTTP_UNAUTHORIZED) {
            logger.debug("Responscode:  " + c.getResponseCode());
            throw new IOException();
        }
    cookie = c.getHeaderField("set-cookie");
    if (cookie == null) {
        throw new IOException();
        }
    return cookie;
        } catch (IOException e) {
            throw new SJConnectionException();
        }
    }
