User-Agent:       Mozilla/5.0 (X11; U; SunOS sun4u; en-US; rv:1.1b) Gecko/20020818
Build Identifier: Mozilla/5.0 (X11; U; SunOS sun4u; en-US; rv:1.1b) Gecko/20020818

This problem appears both on Sun described above and on PC/Win2000 using
Mozilla 5.0 (Windows, U, Windows NT 5.0, en-US, rv 1.1b (Gecko 20020805)
I was able to download the file described below with IE 6.0, so this does
not appear to be a server problem.



Reproducible: Always

Steps to Reproduce:
1.Display http://www.sun.com/solutions/blueprints/tools/
2.Click on link "fspc-2.tar.Z and sidekick.sh.Z"
3.In the javascript popup window accept the license
4.Click on "Download sidekick.sh" in the popup window to download it.
5.Save file to disk

Actual Results:  
File appears to download but has zero length.

Expected Results:  
Downloaded a 5038 byte file in compressed (.Z) format

Note:  I can download the other file on the same popup page successfully
in both above versions of Mozilla.

I think it is a cookie or script error. Both files give this when checking:

curl --head "http://www.sun.com/blueprints/tools/sidekick.sh.Z"

The actual location is somewhere else, determined by the server.

For what its worth, here is the output from wget when downloading the file:

I can reproduce this on solaris using nightly 2002110822.

After agreeing to the license, there are two files available for download, a
.tar.Z and a .sh.Z file. Mozilla can download the .tar.Z file but not the .sh.Z
file. The urls for these files are identical save for the basename component,
and they're simple URLs; there are no obvious cookies or JS involved in actually
downloading the files. I have no trouble downloading the files using lynx with
the direct URLs.

I ran snoop while trying to download the file through mozilla. Mozilla follows
the 302 redirection and downloads the content from the redirected URL; it just
doesn't save it to the local destination file.

I suspect this has something to do with the file's MIME type. The file is
identified as application/x-sh. Maybe mozilla has some restriction on this mime
type or is simply mishandling it.

Attachment: URLs from the download page

These are the links from the download page, both in their original form, and
after redirection by the web server.

The behavior I'm seeing is that I can download sfpC-1.2.tar.Z  using either of
the links. With sidekick.sh.Z, the browser goes through the motions of
downloading it (and a network trace confirms that it downloaded the content)
but the resulting local file is zero length. Note the second file has a MIME
type of "application/x-sh".

Comment 5

[Kenneth Herron]

I just tested this again and I can't reproduce it. The .sh.Z links download
fine. I'm using build id 20030212 on solaris 8/sparc.

Hugh, could you test this with a recent version of mozilla and see if it's
working for you?

Comment 6

[Hugh Coomes]

 I just tested it again with my own build of 1.3b on Solaris 9/sparc
using Sun compiler on 20030208.  Both files download OK.

I also tested with the downloaded 1.2.1 release for Solaris/sparc.  Get zero
length file in that version.

[Boris Zbarsky [:bzbarsky]]

Ah, ok.  This is a duplicate of a problem we had with .Z files specifically....
