Sending the "Content-Length" header fixed the problem. PDFs now appear
inline and with their expected contents. I haven't diffed the code between
2.8 and 2.9, but I'm guessing that Zope used to send that header by default
but no longer does.

Your PDF file appears to be small.
I am also surprised that in your earlier post you returned
the "File" object itself. I would rather expect
"str(fileObject.data)".

No, it's still there (and still set to "inline"). I did, however, follow David H's advice to add the Content-Length header.

Nope - customers are actually getting a single blank page and nothing else. We could live with a blank tab if that was the only problem.

I had similar problems too. This seems to work with IE:
theFile=open( self.pdfpath,'rb')
result = theFile.read()
RESPONSE.setHeader('Content-Type','application/pdf')
RESPONSE.setHeader("Content-Disposition","filename=report.pdf")
RESPONSE.setHeader('Content-Length',len(result))
RESPONSE.write(result)

Re: [Zope] Content-Disposition is driving me batty
Would some IE users please let me know whether they can view this PDF normally? http://web2.xrsnet.com/publicstore/download?filename=print.pdf&password=foo Any speculation about what might be causing this is extremely welcome. I'm *not* looking forward to rolling back to 2.8.x (and Python 2.3) at this point. I am running IE7 beta 3 -- on my machine the pdf file seems to load -- so no content disposition problem but there are messages about missing fonts from the PDF reader *7.0.8 btw) -- no real information is displayed so I am guessing this is "abnormal" by your definition. ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
