Hi,

I'm generating a dynamic PDF file using a namespace taglib, and a XSL
transform using FOP.  However, I am struggling because I cannot seem to get
my PDF get generated consistently...  Oftentimes, a request from the browser
will time-out, but at other times, it works perfectly.  I have found no
pattern as to when it fails...  I have tried each of the Cocoon FAQ
suggestions for getting IE to work correctly with FOP generated PDFs, but
this problem is plaguing every browser that I have (and creating a servlet
and/or changing the file extension to ".pdf" has not helped with the
consistency).  Thanks for any
suggestions that anyone might have...

I am using Cocoon 1.8, Tomcat 3.2 b6, FOP 0.13

Thanks for taking a look!

-Scott
