asp.net 下载大文件时，不能操作其他页面，求解

asp.net 下载大文件时，不能操作其他页面，必须等文件下载完了才能操作其他页面这个可怎么办 asp.net 下载大文不能操作其他页面 --------------------编程问答-------------------- 遇到过类似的问题，整个局域网的用户都瘫痪了，记得当时是iis设置了啥子就好了，上网看看呢 --------------------编程问答-------------------- 把文件服务器与网站服务器分开 --------------------编程问答--------------------

把文件服务器与网站服务器分开

大神除了这个还有别的方案吗，我写个线程行不行，代码
  while (dataToRead > 0)
            {
                // Verify that the client is connected.
                if (Response.IsClientConnected)
                {
                    // Read the data in buffer.
                    length = iStream.Read(buffer, 0, 10000);

                    // Write the data to the current output stream.
                    Response.OutputStream.Write(buffer, 0, length);

                    // Flush the data to the HTML output.
                    Response.Flush();

                    buffer = new Byte[10000];
                    dataToRead = dataToRead - length;
                }
                else
                {
                    //prevent infinite loop if user disconnects
                    dataToRead = -1;
                }
            }
        }

我认为是不是因为这个Response 写的慢需要时间那么我可以不可以写个线程，但是网页里写线程我害怕有问题。。。 --------------------编程问答--------------------

怎么设置的，你说的那个是不是直接全部写到内存里我用的是大文件下载方法   while (dataToRead > 0)
            {
                // Verify that the client is connected.
                if (Response.IsClientConnected)
                {
                    // Read the data in buffer.
                    length = iStream.Read(buffer, 0, 10000);

                    // Write the data to the current output stream.
                    Response.OutputStream.Write(buffer, 0, length);

                    // Flush the data to the HTML output.
                    Response.Flush();

                    buffer = new Byte[10000];
                    dataToRead = dataToRead - length;
                }
                else
                {
                    //prevent infinite loop if user disconnects
                    dataToRead = -1;
                }
            }
        }
是这种，服务器倒是不会卡死就是下载的时候无法操作其他页面 --------------------编程问答-------------------- 有没有人能帮下忙啊 --------------------编程问答--------------------             DownAdress = dimm + DownAdress;
            if (!File.Exists(Server.MapPath(DownAdress)))
            {
                Response.Write("下载的文件不存在!");
                Response.End();
                return;
            }
            using (FileStream fso = new FileStream(Server.MapPath(DownAdress), FileMode.Open,FileAccess.ReadWrite,FileShare.Inheritable))
            {
                string[] filename=DownAdress.Split(new char[]{'/'});
                int len = Convert.ToInt32(fso.Length);
                byte[] FileObj = new byte[len];
                fso.Read(FileObj, 0, len);
                Response.AddHeader("Content-Disposition", string.Format("attachment; filename={0}", HttpUtility.UrlEncode(filename[filename.Length - 1]), System.Text.Encoding.UTF8));
                Response.AddHeader("Content-Length", len.ToString());
                Response.ContentType = "application/octet-stream";
                Response.Charset = "UTF-8";
                Response.ContentEncoding = System.Text.Encoding.UTF8;
                Response.BinaryWrite(FileObj);
                //Response.Flush();
                //Response.Clear();
                fso.Close();
            } --------------------编程问答-------------------- 用后台线程下载，采用回调函数报告下载进度，并且随时可以取消下载。 --------------------编程问答--------------------
