Downloading generated PDF behavior different with apache in front of appserver

[Doug Leeper <do...@yahoo.com>]

All,

We have an application that generates a PDF (via PD4ML) and sends it back in the 
same request.  This works fine and dandy when accessing our app server 
(weblogic/http) directly.  However, when we access the same functionality but 
via Apache and SSL to weblogic, we get a message that the resultant file is 
corrupted.  Not sure why this is occurring.   It appears that stream is being 
closed before the content upload has been completed.  We have static PDF served 
up via apache/weblogic that don't have any problems.

Does anyone have any idea where I need to start looking?  I am assuming this is 
not a Wicket issue as it works when the appserver is accessed directly but could 
be wrong.

Thanks
- Doug

Are you using IE?

There are many troubles generating PDF over SSL.

See for an example :

If you google "IE PDF SSL", you will find many answers.

Here's the workaround I use in my wicket applications (i'm generating PDF
with jasperreports) :
                WebResponse response = (WebResponse)
getRequestCycle().getResponse();
                response.setDateHeader("Expires", -1);
                response.setHeader("Pragma", "public");
                response.setHeader("Cache-Control", "public");

Regards,

Gabriel.
