Yes, if you use HTTP cleartext transport, you can use a packet
sniffer and grab the cookie. But the normal hijack route is by
copying and pasting URLs into an email that gets passed around.
So one thing I do is only allow one concurrent login (IP address) per
userrefernce. This limits the problem nefarious to co-workers in the
same NETed subnet The downside is that some users close their window
mistakenly without logging out, and then they can't login again until
the previous session times out. But we allow them to check a box to
force their old session to expire.

Could someone spoof a cookie's value just like someone could spoof
a user ref argument to do session hijacking?

Yes, but that doesn't solve any of the issues that arise from using
it in a url, you have the same issues, when you don't just use the
cookie methods.

You can also pass UserReferenceArgument as a hidden argument,
which drops it out of the URL...
I believe it must be in this form <input type="hidden"
name="_userReference" value="<@UserReferenceArgument>">
If I am in error on the format, someone on the list more
knowledgeable can correct this .....

Folks I'm dealing with do not like cookies, candies or anything
sweet - spent a lot of time making sure that I was passing
userref in the url to avoid cookies. I'm just gonna see if my isp
can do something about their router, unless my xserve is doing
this NAT, even though its turned off.
Thanks for your help on this Dave, William & Robert!

Yes, they are in the URI, you can see in the log:
_function=validate_user&_UserReference=58FA321F03B02D3E447F5B62
Remove userreference from URI, and only use cookies.

Look in the archive on session hijacking.

Hello all!
I looked at my witango log today and it seems like the same
userreference was assigned to two different users, seconds
apart while both were accessing diff. apps.
What's so odd is that the server address of xxx.xxx.xxx.xxx is
being logged as the clients ip. How can this be?
