StreamingResolution +IE6 problem

Rate this Message:
Hi all,
I'm having a problem with IE6. My code is as follow: ------------------------------------------------------------------------------- BufferedInputStream bis = new BufferedInputStream(new FileInputStream("c:/bla.pdf")); ByteArrayOutputStream baos = new ByteArrayOutputStream(); response.setHeader("Expires", "0"); response.setHeader("Cache-Control", "must-revalidate"); response.setHeader("Content-Disposition", "attachment;filename=\"bla.pdf\""); response.setHeader("Pragma", "public"); response.setContentType("application/pdf"); int bytesRead; byte[] buff = new byte[4096]; while ((bytesRead=bis.read(buff)) > 0) { baos.write(buff, 0, bytesRead); } bis.close(); baos.close(); response.setContentLength(baos.size()); baos.writeTo(response.getOutputStream()); ------------------------------------------------------------------------------- THat will popup a dialog, where user can choose to open, save or cancel. Saving is fine, but choosing to 'open' it in IE6 will open acrobat reader, with error message 'file cannot be found'. I've noticed that some guy encountered the same problem: http://www.mail-archive.com/stripes-users@.../msg02126.html and I tried to follow his suggestion without any luck. (somehow my http response has cache-control: no-cache ) This only happen with stripes. If I do the following in a plain servlet: ------------------------------------------------------------------------------- BufferedInputStream bis = new BufferedInputStream(new FileInputStream("c:/bla.pdf")); BufferedOutputStream bsos = new BufferedOutputStream(response.getOutputStream()); response.setHeader("Expires", "0"); response.setHeader("Cache-Control", "must-revalidate"); response.setHeader("Content-Disposition", "attachment;filename=\"bla.pdf\""); response.setHeader("Pragma", "public"); response.setContentType("application/pdf"); int bytesRead; byte[] buff = new byte[4096]; while ((bytesRead=bis.read(buff)) > 0) { bsos.write(buff, 0, bytesRead); bsos.flush(); } bis.close(); bsos.close(); ------------------------------------------------------------------------------- It works ok. Has anyone ever had this problem before? Thanks in advance for the help! -- Best regards, WiB ------------------------------------------------------------------------------ Come build with us!

Hi Alex,
do you somewhere use the stripes-provided StreamingResolution class? Passing in the parameters ContentType, InputStream and filename creates a working StreamingResolution for me - in IE6, too. Manipulating the response itself should not be neccessary as well as (anonymously) subclassing StreamingResolution.

I had similar problem using HTTPS and disabling caching. It seems that IE reads attached PDF file, saves as temporary file and then removes it from disk before serving it to external reader, make it Adobe Reader or anything. I changed Expires header to now + couple seconds and it works fine. ------------------------------------------------------------------------------ Come build with us!

Hi guys...
Thanks a lot for the reply. It turns out that the bug was due to something else. We store something in the cookie. Which causes the following http header to be sent Cache-Control: no-cache="set-cookie" and when IE6 sees this header, it deletes the file :( the fix for us, is not to store anything in the cookie :( Regards, On Fri, Oct 23, 2009 at 2:18 AM, RomeoAD <romeoad@...> wrote:

We ran into this problem and found a solution a few months ago.
Setting the Cache-Control header to "" (blank) or "private" seemed to fix the https and PDF issue from what I recall.
