/**
 * A helper method to send or retrieve data through HTTP protocol.
 *
 * @param url The URL used in a GET request. Null when the method is
 *         HTTP_POST_METHOD./*w  ww. j a  va2 s. c  om*/
 * @param pdu The data to be POST. Null when the method is HTTP_GET_METHOD.
 * @param method HTTP_POST_METHOD or HTTP_GET_METHOD.
 * @param isProxySet If proxy is set
 * @param proxyHost The host of the proxy
 * @param proxyPort The port of the proxy
 * @param resolver The custom name resolver to use
 * @param useIpv6 If we should use IPv6 address when the HTTP client resolves the host name
 * @param mmsConfig The MmsConfig to use
 * @return A byte array which contains the response data.
 *         If an HTTP error code is returned, an IOException will be thrown.
 * @throws com.android.mms.service.exception.MmsHttpException if HTTP request gets error response (>=400)
