[Zope] pdf generator troubles

[Erik Myllymaki]

DTML calls an external method to show a PDF file inline:

<dtml-call "RESPONSE.setHeader('content-type','application/pdf')">
<dtml-call
"RESPONSE.setHeader('Content-Disposition','inline;filename=somefile.pdf')"><
dtml-var expr="pdftest('C:\somefile.pdf')">

external method is like this:

--------------------------------------------------
def pdftest(pdf_filename):

     import sys
     f=open(pdf_filename)
     y = f.read()
     f.close()
     return y
---------------------------------------------------

But I always get a *File is damaged* error no matter what PDF file I give
it.  Testing the function outside of zope, it returns only part of each PDF.
as soon as it hits STREAM it stops...?

Zope 2.3.2 on WinNT Server 4.0

Note:tested ONLY with IE 5.5 on win2k
