I have an .aspx page where I'm manually setting headers to force a download of a pdf file. It works fine in IE, but in chrome and firefox 8.0, it's giving an error.

我有一个.aspx页面,我手动设置标题以强制下载pdf文件。它在IE中运行良好,但在chrome和firefox 8.0中,它给出了一个错误。

I finally tracked down the source of the problem to the content-disposition header being sent twice but I have no idea how or why it's being set the first time.

我最终将问题的来源追溯到两次发送的内容处置标题,但我不知道它是如何或为什么第一次被设置。

The first instance of the header is just: Content-disposition: Attachment The second is: Content-Disposition:attachment; filename=download.pdf <-- this one set by code

标题的第一个实例是:Content-disposition:Attachment第二个是:Content-Disposition:attachment; filename = download.pdf < - 这一个由代码设置

is IIS taking over somehow and adding this first instance of the header? If so, how can I toggle it to NOT do that?

IIS以某种方式接管并添加头的第一个实例?如果是这样,我怎么能把它切换到不那样做?

EDIT: adding the code that sets the headers

编辑:添加设置标题的代码

Response.ContentType = "application/pdf";
                Response.AddHeader("Content-Disposition", "attachment; filename=" + filename);
                Response.WriteFile(fname);
                Response.Flush();
                Response.End();
