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

[Tue Sep 08 10:15:17.455 2009] [2500:2532] [trace] jk_lb_worker.c (1065): enter
[Tue Sep 08 10:15:17.455 2009] [2500:2532] [debug] jk_lb_worker.c (1114):
service sticky_session=1 id='empty'
[Tue Sep 08 10:15:17.455 2009] [2500:2532] [trace] jk_lb_worker.c (903): enter
[Tue Sep 08 10:15:17.455 2009] [2500:2532] [debug] jk_lb_worker.c (997): found
best worker ndb1 (ndb1) using method 'Request'

second request beautiful found the worker with the correct route

[Tue Sep 08 10:15:17.533 2009] [2500:2532] [trace] jk_lb_worker.c (1065): enter
[Tue Sep 08 10:15:17.533 2009] [2500:2532] [debug] jk_lb_worker.c (1114):

[Tue Sep 08 10:15:17.533 2009] [2500:2532] [debug] jk_lb_worker.c (950):

[Tue Sep 08 10:15:17.533 2009] [2500:2532] [debug] jk_lb_worker.c (964): found
worker ndb1 (ndb1) for route ndb1 and partial sessionid

[Tue Sep 08 10:15:17.533 2009] [2500:2532] [trace] jk_lb_worker.c (967): exit

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

[Tue Sep 08 10:21:08.705 2009] [3936:3008] [trace] jk_lb_worker.c (903): enter
[Tue Sep 08 10:21:08.705 2009] [3936:3008] [debug] jk_lb_worker.c (942):

best worker ndb1 (ndb1) using method 'Request'

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

blah blah blah represents some random mumbly jumbly from the request,
definitely not the JSESSIONID
