Hi
I have configured tomcat cluster [v6.0.20] on linux box with mod_proxy/mod_proxy_ajp [tomcat 6/Redhat 5/stickysession also turned on for load balancer] on two different nodes. Each node is running one tomcat instance. I inserted cluster element under engine and turned on jvmroute by setting up mod_proxy/mod_proxy_ajp. I also tested with mod_jk, but both cases failed. Anyway, when I turned on form authentication, it always generates the error for the fist login attempt, but the second login attempt always succeeds. I am getting: HTTP Status 400 - Invalid direct reference to form login page When I switched from form to basic authentication, the first login attempt always succeeds. When I turned off mod_proxy/mod_proxy_ajp or mod_jk with very basic simple cluster configuration also has this problem if I tried to use two nodes [two physically different node by inserting cluster element under engine element on server.xml]. If I moved cluster element to under host element by setting up two tomcat instances on the same machine/node, the first login attempts succeeds with form authentication. Is there any way to make form authentication work for the fist login attempt with two different nodes? I am using clustersinglesignon. Even if I switch to singlesignon, the result is consistent. Any idea? Thanks, yasushi
