HttpWebRequest返回Section=ResponseStatusLine的问题

[hywok]

想写个小工具用WEBrequest从：http://www1.97down.info/qb/file.php/LV0OB8F.html页面下载文件。可是即使是访问这个页面也会返回The server committed a protocol violation. Section=ResponseStatusLine错误。用IE9捕获到访问这个页面的request headers:

Key Value

Request body是空。

如果点击下载，用IE9捕获的request headers是：
Key Value

Accept text/html, application/xhtml+xml, */*

Request body是：
type=torrent&id=LV0OB8F&name=NHDTA-130

只有30分了。希望哪位闲着的大牛帮个忙。

关于加useUnsafeHeaderParsing= "true "这个已经试过了，没有作用

现在Post请求文件的已经解决了，get请求这个html的有高手可以解决吗？

难道没有人关心~
