IE8 PDF wont download

#26781

I am using PD4ML 380fx6 taglibs which generates a PDF. This works fine in Chrome, Firefox and IE9 +.

But when I do it in IE8 I get the attached error.

This is the transform tag I am using

<pd4ml:transform
screenWidth="1100"
pageFormat="A4"
pageOrientation="portrait"
pageInsets="15,15,15,15,points"
inline="false"
generateHyperlinks="false"
debug="true"
outline="headings"
fileName="Report.pdf">
<%@ taglib uri="http://tiles.apache.org/tags-tiles" prefix="tiles"%>

Http Response headers

Cache-Control:private
Cache-Control:no-cache
Connection:close
Content-disposition:attachment; filename=Report.pdf
Content-Length:10646
Content-Type:application/pdf
Date:Wed, 19 Sep 2012 16:07:16 GMT
Expires:0
Pragma:no-cache
Pragma:cache
Server:Apache-Coyote/1.1

Anyone have any ideas?

I think this may be related to it.

Any idea how to fix this using the PD4ML TagLib?

It looks like the problem is caused by a caching of documents, downloaded by HTTPS. Please correct if I am wrong.
It was a known issue of older PD4ML JSP taglib versions, until we found a safe HTTP header directives set.

Currently PD4ML taglib sets only the following HTTP cache control directives:

((HttpServletResponse) sr).setHeader("Pragma", "cache");
((HttpServletResponse) sr).setHeader("Expires", "0");
((HttpServletResponse) sr).setHeader("Cache-control", "private");

In your case there are some other cache controls (including conflicting with the above) – probably the hosting application is configured to add them to each reply. Try to switch it off for PDF generating JSPs.

PD4ML, tankyou ! Works like a charm =)

I also have add cache-control: no-store, no-cache. See lines bellow:

response.setHeader("Pragma", "cache");
response.setHeader("Expires", "0");
response.setHeader("Cache-control", "private");
response.setHeader("Cache-Control", "no-store, no-cache, must-revalidate");

Again, tankyou!
