转换服务器用.net开发，win7平台

网站采用apache 的 .htpasswd http认证 采用密码保护用户上传的doc等文档源文件。

fp服务器自动从web中依次取得用户上传的doc文档，并且转换后回调web上传接口，实现文档的在线转换

下面的代码是下载web上的源文档用于在线转换

 try
            {
                String url = "http://localhost:82/api/T1yAdWXgdGXXb1upjX.jpg";
                String fileName = url.Substring(url.LastIndexOf("/") + 1);
                String refer = url.Substring(0, url.LastIndexOf("/") + 1);

                System.Net.HttpWebRequest req = System.Net.HttpWebRequest.Create(url) as System.Net.HttpWebRequest;
                req.AllowAutoRedirect = true;
                req.Referer = refer;
                /*发送http认证*/
                req.Credentials = new NetworkCredential("xzy", "xzy");

                System.IO.Stream stream = res.GetResponseStream();
                byte[] buffer = new byte[32 * 1024];
