Dowloading attatchments with IE...

[Joe Smargie]

    I'm using-
    IMP: 2.3.6
    Apache: 1.3.9 w/PHP 4 build 5 (not using PHPLib)
    IE 5.5 SP1 and Netscape 4.76

    I can't download things that are attatched to an email using IE. When I
click on the attachment, I get get a blank window instead of a dialog save
box. The code in view.php seems to be set to issue the proper headers:

    case DOWNLOAD_ATTACH:
         /* This should force a save file dialog. */
         header('Content-Type: application/octet-stream');
         header('Content-Disposition: attachment;filename="' . $mime['name']
. '"');
         break;

    However I snooped HTTP talk going between the browser and server. The
proper header doesn't seem to be passed out when using IE:

<request sent when I click on download link>
HTTP: GET
/horde/imp/view.php?mailbox=INBOX&index=55&bodypart=3&actionID=13&mime=YTo2O

But when I use netscape the server spits out the headers specified by the
header() command in view.php

<request to server>
HTTP: GET
/horde/imp/view.php?mailbox=INBOX&index=55&bodypart=3&actionID=13&mime=YTo2O

So it seems that IE is doing something that cause Apache not to send out the
headers which are dumped into the header table using header(); in view.php.
However the requests look ok for each of them. I know that IE is screwey and
doesn't properly do mime, but the bottom line is people use IE and so I need
to try and work around this somehow. Any ideas?

    A thousand thanks,
    -Joe S.

P.S. Please do not respond with "well I tried d/l'ing attatchments with IMP
2.2.blah with both netscape and IE and it worked just fine. blah blah
blah.." As I said I'm using IMP 2.3.6; I realize this is pre-alpha but it
seems to work pretty well with the execption of this one issue.
