一旦编写了标头内容，就无法将其更改为其他内容.我不确定您要做什么是否行得通.您需要解决它.

解决这些问题的一种方法是，在新窗口中打开下载链接，然后可以从父窗口重定向到其他窗口.

Once you write your header content you can''t change it to something else. I''m not sure if what you want to do will work. You need to work around it.

One way to work around them is, open your download link in new window and then you can redirect to different window from the parent window.
