Close to that:

http://www.myserver.com/mywebapp/test.jsp;jsessionid=123456789.tomca1
http://www.myserver.com/mywebapp/test.jsp;jsessionid=123456789.tomca2
http://www.myserver.com/mywebapp/test.jsp;jsessionid=123456789.tomca3

assuming that tomca1, tomca2 and tomca3 are the jvmRoutes defined in the 
server.xml of the three nodes.

You can replace 123456789 by an even shorter string, I think even an 
empty string would work, as long as there is a dot before the jvmRoute.

Rainer
