1156672 - IE9 displays attachment instead of downloading it when attachment name is set to be longer than 38 characters

Status: RESOLVED INVALID

(Bugzilla :: Attachments & Requests, defect)

Description

[rafik]

Attachment: display error.png

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.118 Safari/537.36

Steps to reproduce:

I tried to download an .xlsx attachment file.


Actual results:

I can download it using firefox and chrome, but in IE it displays a sort of encrypted page.


Expected results:

i changed the name of the attachement and the file can be downloaded.
i tested the length i found that with more than 38 character internet explorer can't download the file and displays an incripted page instead.

We have encountered a very similar issue in our instance of version 4.2.5

In our case, we saw IE9 open a .docx file as a zip file. We found that if the attachment's filename was less than 48 characters, it would open the file in MS word as expected.

If the filename was 48 characters or longer, IE9 would ignore the mime-type being declared by Apache and try to determine the mime-type by examining the contents of the file.

In my understanding, this is solely an IE9 bug and not the fault of Bugzilla.

Yes, I agree. So closing as invalid, a.k.a not a Bugzilla bug.
