[jcifs] url-pattern problem with internet explorer (ie resending NTLM-authentication)

[floooh]

hey there,

i made a tiny web-app (kind of "hello-world") with google's gwt and deployed it
on a jboss-server. there's a remote-service on the server which can be called
from the client. (watch http://rapidshare.com/files/34058146/sso.war.html for
details - it's REALLY not many lines of code!)

everything worked fine on both firefox and internet explorer.
then i changed the url-pattern from /* to /SSO.html - from now on i would get an
error whenever trying to call a function on the server. (stacktrace at the end
of the post)

i tried to figure out what was going wrong and even used a sniffer to have a
look at the network messages between client and server.
what i got was surprising (at least to me):
with firefox there's one ntlm-authentication when loading the page and none when
calling the function on the server.
whereas IE sends some ntlm-authentication-stuff again and again.

that's fine when having the url-pattern /*. IE get's some ntlm-stuff back and
everything's working as it should. but with a different url-pattern there's no
ntlm-answer from the server, but an error...


i would really appreciate some help on this. if i don't get it to work i'd have
to think about looking for a different solution.

regards,
         florian



and here's the stacktrace from the server log (i could also send/upload the
network log (.acp-format: http://analyzer.polito.it/), if someone thinks he
might figure something out knowing what server and client are doing in detail):
