the class HttpUtil method downloadData.

/**
 * Download the data from an URL.
 *
 * @param url the URL of the data to be downloaded
 * @param contentTypeRegex the REGEX the content type must match; null to ignore the content type
 * @param scanTypeInContent true to allow the scan of data to determine the content type if not found in the headers
 * @param maxContentLength the maximum data size in bytes to trigger the download; any negative value to ignore the
 *            data size
 * @param timeout the socket timeout in milliseconds to wait for data
 * @return a RawType object containing the downloaded data, null if the content type does not match the expected
 *         type or the data size is too big
