----------------------------------
The case of Content-Disposition has not effect. I investigated this issue last
year and created a custom Result to investigate every header combination.
*My final advice is to NOT use inline disposition for PDFs. Some users
appreciate the "Open With or Save prompt".*
There are several IE issues if you really want an inline response:
1. The content length header MUST be present
2. the *request* URI must contain .pdf, irrespective of the filename. ie. it
must contain .pdf *anywhere* in the URI

If you're using SSL, you need you need to ensure the PDF file is at least 8kb
[1], include the Cache-Control: no cache header, include the Cache-Control: no
store header, ensure your users are using IE6SP1+ and that they have the "save
encrypted pages to disk checkbox turned off [2]

Still worth the effort?
> Result type stream issue with inline file download in IE6

> Key: WW-2647
> URL: https://issues.apache.org/struts/browse/WW-2647
> Project: Struts 2
> Issue Type: Bug
> Components: Other
> Affects Versions: 2.0.11
> Environment: Tomcat 5.5.17 as web server
> Using Eclipse 3.3 as IDE
> Reporter: Ashish Sharma
> Fix For: 2.1.3
>
>
> Hi,
> I am using struts 2.0.11.
> I am facing an issue in downloading pdf files as inline (open file in same
> browser window), in IE6.
> Instead of opening the file in the browser window, pdf is opened separately
> and browser window remains open with nothing inside it.
> Following is the result defined for my action.
> <result name="success" type="stream">
> <param name="contentDisposition">inline;filename="abc.pdf"</param>
> <param name="contentType">application/pdf</param>
> <param name="inputName">reportStream</param>
> </result>
> However this code seems to work fine for both IE7 and Firefox 2.0
> Also this is not a browser issue with IE6, as i can open the pdf file in
> same window using the conventional approach below:
> HttpServletResponse response = ServletActionContext.getResponse();
> response.reset();
> response.setContentType("application/pdf");
> response.setContentLength(l_data.length);
> response.setBufferSize(l_data.length);
> response.setHeader("Content-Disposition", "inline; filename=\"abc.pdf\"");
> OutputStream out = response.getOutputStream();
> out.write(l_data);
> out.flush();
> response.flushBuffer();
> Can you please look into this.
> Thanks,
> Ashish
