isapi_redirect.dll - load balancing issues with sticky sessions

Hi everyone,

i have an issue with isapi_redirect.dll:

I'm testing an application (struts, hibernate and jsf), that
runs in
multiple tomcat instances.

On the webserver (IIS6) i have the isapi_redirect.dll module
installed
(version 1.2.20 i think)

As long as loadbalancing is not activated everything runs
smoothly
(... only one instance is used).

But as soon as I balance the application with a
loadbalanced_worker -
the requests are randomly distributed (based on the lbfactor
of
course) to the application instances - thus loosing all
session data
from one request to the next.
I have the sticky_session option enabled of course - but it
doesn't
seem to do what i expect of it 

Can anyone point me in the right direction on this one?

Thanks in advance,

cheers

Moritz
