求助关于Webwork当中如何将PowerPoint文档直接在IE当中打开，而不是下载？

Question

在RFC2183中定义了使用Content-Disposition的两种标准方式:inline和attachment,inline表示直接处理,而attachment则要求用户干预并控制接收程序如何处理数据内容.在HTTP应用中,只有attachment是Content-Disposition的标准方式.
书上抄来的.所以只用这句:response.setContentType("application/vnd.ms-powerpoint");看,别的全去了

Answer 1

这么说HTTP只用attachment没有inline，这样的话，浏览器是如何区别直接打开还是下载的
因为我程序里pdf的文件可以在IE里面打开，而ppt的就不能。很晕

Answer 2

我也遇到了同样的问题,我要的是直接打开pdf,不需要弹出对话框提示保存下载,应该是和注册表有关系,同样设置attachment是调用应用程序打开,设置inline是在网页内打开.现在还没有解决,正在找办法!

Answer 3

在web.xml中配置MIME类型,这样他就不会提示下载而是打开了
