I've got some trouble with displaying pdfs in IE7 (which were generated by R&OS' ezpdf).
我在IE7中显示pdf有些麻烦(由R&OS的ezpdf生成)。
IE7 with Acrobat Reader 8.1.2. says "The page cannot be displayed"
IE7与Acrobat Reader 8.1.2。说“页面无法显示”
Other Browsers (like FF3/Acrobat 8.1.2. or IE6/Acrobat 7) have no problem with the file.
其他浏览器(如FF3 / Acrobat 8.1.2。或IE6 / Acrobat 7)对文件没有任何问题。

Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Pragma: no-cache
Cache-Control:no-store,no-cache,must-revalidate,post-check = 0,pre-check = 0 Pragma:no-cache
...so IE won't store the file in the Temporary Internet Files folder. However the mechanism used to directly 'Open' a file from the browser in IE often requires it to be opened from inside Temporary Internet Files. Directly opening a file from a browser is generally unreliable, especially in IE; 'Save as' works better.
...所以IE不会将文件存储在Temporary Internet Files文件夹中。但是,用于在IE中直接从浏览器“打开”文件的机制通常需要从Temporary Internet Files中打开它。直接从浏览器打开文件通常是不可靠的,尤其是在IE中; “另存为”效果更好。
Consider replacing the cachebusting headers with an alternative method, such as add a '?randomstring' parameter to the URL. Also consider adding a "Content-Disposition: attachment; filename=..." header, which will stop a plug-in trying and failing to display the file in the browser UI.
考虑使用替代方法替换cachebusting标头,例如向URL添加“?randomstring”参数。还要考虑添加“Content-Disposition:attachment; filename = ...”标题,这将阻止插件尝试并且无法在浏览器UI中显示该文件。

I think I've solved the problem.
我想我已经解决了这个问题。
The problem is not on the server-side but on the client-side. The generated PDF is being displayed in a popup-window (javascript: window.open) and IE7 chokes on it.
问题不在服务器端,而在客户端。生成的PDF显示在弹出窗口(javascript:window.open)和IE7上。
When I open a html-file in the popup which is redirecting to the PDF it works.
当我在弹出窗口中打开一个重定向到PDF的html文件时,它可以工作。
