Hi Guys,
Thanks for your feedback with this issue. This has been making me crazy for
such a long time.
I have put this in last night and tested.
<VirtualHost *:80>
JkMount /*.jsp loadbalancer
JkMount /*.jsf loadbalancer
JkMount /* loadbalancer
JkMount /servlet/* loadbalancer
JkMount /a4j_3_2_2-SNAPSHOTorg/* loadbalancer
JkStripSession On
It does not work again. Strange it works for a while then when the session
times out there seems to be an issue.

I am going to try the
RewriteRule /contextPath/(.*);jsessionid=[0-9A-Z]*(.*)
/path/to/webapps/contextPath/$1$2 [L]
I will let you know how it goes.
Fell free to add anything you might have thought of to this thread. All is
appreciated.
Thanks
