OK, I found the solution and it's really wacky. Apparently IE is misreading the header, and if the word "attachment" shows up anywhere on the Content-Disposition line, including in the file name itself, it will spawn the dialog. For example, the following will cause IE to launch the open/save/cancel dialog every time: Content-Disposition: inline; filename="spb_bar_codes_attachment.pdf" While the following will launch the plugin every time: Content-Disposition: inline; filename="spb_bar_codes_xyz.pdf" -----Original Message----- From: Phillip Hutchings [mailto:sitharus@gmail.com] Sent: Wednesday, January 19, 2005 3:50 PM To: Nathaniel Wingfield Cc: zope@zope.org Subject: Re: [Zope] http header question On Wed, 19 Jan 2005 12:24:25 -0500, Nathaniel Wingfield <NWingfield@dixon-hughes.com> wrote:

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?
I had this problem with PHP powered site. IE would always ask to save and never display with the plugin. Even when the headers were identical it wouldn't work, but everything other than IE worked. I just ended up serving directly with Apache. A quick thing first, the Content-Disposition header should look like this: Content-Disposition: inline; filename="attachment.pdf" to make IE display in the PDF plugin. -- Phillip Hutchings http://www.sitharus.com/ sitharus@gmail.com / sitharus@sitharus.com ID:[{20050119155530.24590.7625540730-66.208.180.43}] _______________________________________________ CONFIDENTIALITY NOTICE This e-mail is intended only for the addressee named above.
