Have an IIS 6 Web site with isapi redirects to two tomcat engines with sticky
support enabled.
isapi filters are the 1.2.28 with chunked encoding suport.
When only a single isapi is loaded into IIS all is fine
here is the output of the isapi log with loglevel set to trace
first request as expected no sticky yet with id =empty

in this case the jvmroute parameter has been set to ndb1 in the first tomcat
If I add another instance of the isapi dll into the web site I get an unusual
service sticky_session log entry

The service sticky_session=3682862 is incorrect and so is the information after
it and there is no way that stickiness can work
