Well in a production situation there would be one host name used and failover would just change which server the requests to that host name get routed to. In that scenario the same cookies would be used so no problem.
You should be able to use some trickery in your hosts file to mimic this. Add a host name (clustertest perhaps) that points to the first server's IP address, access the site, switch the IP address in the hosts file to the second server, verify that the second server is indeed hit and that the behavior is correct. I'm not sure if you are familiar with working with a hosts file so just know that on all Unix-like systems I have encountered it is found at /etc/hosts and on all Windows systems I have encountered it is found at C:\WINDOWS\system32\drivers\etc\hosts Larry -----Original Message----- From: Artem D.

Servers are configured with jvmRoutes jvm1 and jvm2, i.e. for the first server: <Engine name="Catalina" defaultHost="localhost" jvmRoute="jvm1"> jsessionid request parameter while requesting the first server looks like jsessionid=3E526DD2214AEA5B5C2DAB9C6713AF26.jvm1 When switching to the second server jvm2 suffix is used.
