My application streams pdf files from disk (not zodb) to the user, and I've been writing the http header more or less manually. I've had some strange problems with downloading - one particular third-party pdf plugin acts as if the file can not be found, and Internet Explorer arbitrarily, yet consistently pops the Open/Save/Cancel dialog for 1% of files, while launching a plugin for the other 99%. My header looks like this: HTTP/1.1 200 OK Server: Zope/(Zope 2.7.3-0, python 2.3.4, linux2) ZServer/1.1 Date: Wed, 19 Jan 2005 17:08:30 GMT Content-Length: 20004 Content-Type: application/pdf Connection: close Content-Disposition: filename="attachment.pdf" Is there anything missing or malformed that could be causing trouble?
