[users@httpd] Réf. : Re: [users@httpd] MIME types
Thanks for the advice.
I have downloaded ethereal. But do you know in what type of packet I
should find the header of the DOC file ?

You need to see the header correspondance between Apache and those
clients.
Use a tool like Ethereal (http://www.ethereal.com/) to do this.
If Apache is sending the correct headers, there isn't much you can do from
the server-side, but need to look at the clients. A possible solutions
would
include http://www.mozilla.org/products/firebird/ :)

A much easier way to get Apache's headers
is via the built-in usage of Windows Scripting.
Retrieving a Web Page
http://www.microsoft.com/technet/scriptcenter/other/scroth16.asp
Save the above Windows Script VBScript file into
any folder, using the file name GetHeaders.vbs.
To get all the headers sent from Apache
make these two line changes:
'*** To not get the text of the web page
'*** add the comment makers '*** to the
'*** the below line like the following example.
'***WScript.Echo objHTTP.ResponseText
'*** For headers only comment out the above
'*** line and use the below line.
'**** And for headers:
WScript.Echo objHTTP.GetAllResponseHeaders()
The whole VBScript script is five lines long!
XMLHTTP is the same object that IE uses,
so beware that newer changes to the internal
IE upgrade/security code may have changed
the access mode to XMLHTTP too - Now if IE
is set to offline mode then XMLHTTP may error
out with: GetHeaders.vbs(5, 1) (null): 0x800C0008
So watch XLMHTTP usage with IE online/offline
modes. It may work currently even if IE is set to
the online mode or offline access mode, even for
localhost actions, or it may not (depending on IE
version upgrades etc.). If not working, set IE mode
to online.
For server usage (inside Apache or even non
server usage - does not use IE "parts") use
WinHttp 5.1 like below:
'*** Set objHTTP = CreateObject("WinHttp.WinHttpRequest.5.1")
For local file access.
'*** url= "file://c:\documents and settings\filename.txt"
Once the above VBScript is saved into any
folder, then to run this VBScript, via the built-in
Windows Script Host (WSH) engine, cscript.exe,
open a command prompt window set to the
above saved script's folder, and then type:
cscript.exe GetHeaders.vbs
And of course there is also the free utility
Wfetch.exe.

I take that you mean the header/s of the HTTP response of the .doc file.
Word's internal headers are irrelevant to us.
What should happen when a client requests the document is this:
Client sends request to server:
GET /path/to/word.doc HTTP/1.1
Host: www.domain.tld
etc...
The server responds like this:
HTTP/1.1 200 OK
Content-type: not/sure
Content-length: 99999
...some more headers...
(Word document data)
So, these are the normal HTTP headers you are looking for. I suggest you
start Ethereal on one of the misbehaving clients, start capturing just
before you click the link, and then stop the capture when the it has loaded
the document. Look for HTTP packets starting with "GET /..." (request) and
"HTTP/1.1 200 ..." (response).
