Probably that is what is happening.  Word has some embedded "browser 
capability" (using a part of IE's DLL's), but it probably does not 
support the full set of IE capabilities (like cookies e.g), which may be 
the reason of the OP's problem.

Antonio :
When Word is doing the login, Tomcat returns a re-direct response to the 
original requested page, along with a "Set-Cookie" header containing the 
session-id.  However, Word does not take this Set-Cookie header into 
account, and does not send the Cookie header when it re-requests the 
protected page.  So Tomcat thinks this is a new session, and sends the 
request somewhere else.
Or something of the kind.

You nmay have better luck using the setup whereby Tomcat does not use 
session-id cookies, but embeds the session-id in the URL.  Someone here 
should intervene, and tell you how to achieve this.

Anyway, this is all quite inelegant, and likely to cause variable 
behaviour depending on which browser version is installed, which local 
software is installed, which DLLs and so on.
If this whole thing is supposed to work inside a local Windows-based 
network, for Windows workstations and users already logged-in into the 
Windows domain, then I would suggest that you redesign your scheme to 
work using the Windows Integrated Authentication (aka NTLM).
I have not tried it, but I am quite sure that MS-Word will support this, 
and there are several solutions for supporting this in Tomcat.
