    public HttpWebResponse getUrlResponse(string url,
                                        Dictionary<string, string> headerDict = defHeaderDict,
                                        Dictionary<string, string> postDict = defPostDict,
                                        int timeout = defTimeout,
                                        string postDataStr = defPostDataStr,
                                        int readWriteTimeout = defReadWriteTimeout)
    {
#if USE_GETURLRESPONSE_BW
        //BackgroundWorker Version getUrlResponse
        HttpWebResponse localCurResp = null;
        getUrlResponse_bw(url, headerDict, postDict, timeout, postDataStr, readWriteTimeout);
        while (bNotCompleted_resp)
        {
            System.Windows.Forms.Application.DoEvents();
        }
        localCurResp = gCurResp;

        //clear
        gCurResp = null;

        return localCurResp;
#else
        //non-BackgroundWorker Version getUrlResponse
        return _getUrlResponse(url, headerDict, postDict, timeout, postDataStr);;
#endif
    }

    

从上面的代码中可以看出，此处的getUrlResponse内部的实现，是依赖于是否设置宏USE_GETURLRESPONSE_BW，而去调用对应的BackgroundWorker版本的，还是非BackgroundWorker版本的_getUrlResponse

此处，getUrlResponse，是用来返回HttpWebResponse的，且支持N多参数。
