[Zope] Re: MSIE 6 not opening MIME attachments

[Jim Kutter]

Sorry folks, I figured it out.

Turns out I was sending a Cache Control header elsewhere in the code.

That was preventing IE from saving the file in it's temp internet files folder, and that's why "open" didn't open squat - the file never got cached... In hindsight it makes perfect sense...

Thanks for the pointers, if anyone else runs into this, here's the page that tipped me off to the problem: http://support.microsoft.com/default.aspx?scid=kb;en-us;243717&Product=ie

Thanks for the info regarding the nature of the bug. 

Unfortunately I can't change the URL for a few reasons.

Also changing the disposition to "inline" from "attachment", didn't help either. I think the only option left is to post a warning to IE users...

Hi,

IE only is responsible of this bug : if you specify a "filename" parameter in 
the "Content-Disposition" header, then IE doesn't open the file (you may have 
the same kind of problem with PDF or DOC files).
This problem which appeared in IE 5.0 disappeared with IE 5.5 and came back in 
IE 6.
Just remove the "filename" option and everything should be OK (but you should 
keep a good extension in your URL, otherwise it should fail also, depending 
on your client OS configuration).
