我在 Windows 2008 上有一个 IIS7 网站。从 java-script 我通过 http-handler 编写 mp3 文件：

var audio = document.getElementById("audio");
audio.src = GetMultimedia.ashx?F=" + filename;
audio.load();
audio.play();

获取多媒体.ashx：

 Response.ClearHeaders();
 Response.ClearContent();
 Response.Clear();
 Response.ContentType = "audio/mp3";
 Response.AddHeader("content-length", FileLength().ToString());
 Response.AddHeader("Connection", "keep-alive");
 Response.BufferOutput = true;

   GetFile(ref FileBuffer);  // I get buffer of mp3-file for writing to Response
   if (FileBuffer != null)
   {
     ms = new MemoryStream(FileBuffer, 0, FileBuffer.Length, true);
     if (Response.IsClientConnected == true)
     {
       ms.CopyTo(Response.OutputStream);
       Response.Flush();
      }
   }

问题：在 Windows 上任何浏览器都可以正常工作，但在 Android（Opera，内部浏览器）上 http-handler 工作 12 次（日志如下）。IIS 在此处理程序调用 11 次后写入 retcode 200 0 64。因此，响应中的 mp3 文件与原始文件不同，因为 http-handler 多次调用。
