We r using tomcat 5.5.27. Here is server.xml from one of nodes(I skip all not
important things from my point of view):
<Server port="xxxx" shutdown="SHUTDOWN">
<Service name="Catalina">
<Engine name="Catalina" defaultHost="localhost"
jvmRoute="apps1">
<Cluster
className="org.apache.catalina.cluster.tcp.SimpleTcpCluster" />
</Engine>
</Service>
</Server>
also in web.xml i dont have <distributable/> tag, only servlet and filters setup
so it looks like sticky sessions r in use, am i right ?
After alot of googling i found some notice about <distributable/>
tag in web.xml, is there any howto about clustering ?

Yes, u r exectly right. u used response.encodeURL(), so when cookies r off
i saw http://host/webapp/somePage.jsp;jsession=sessionId.
And yes, every page come with new session id.
