Answer 1

Everything is much simpler with Servlet API 3.0.

Now you can configure it in your web.xml:

<session-config>
    <cookie-config>
        <name>MY_JSESSIONID_YAHOOOOOO</name>
    </cookie-config>
</session-config>

That's it!

Answer 2

I found it in Tomcat at /tomcat/conf/server.xml

server.xml

<Engine name="Catalina" defaultHost="localhost" jvmRoute="instanceName">

5D33F755D8D75EF7C8E840.instanceName

Answer 3

I don't think it's possible at this point - see https://issues.apache.org/bugzilla/show_bug.cgi?id=42419

The last entry states "This has been fixed in 5.5.x and will be included in 5.5.28 onwards" - which is the next point release - 5.5.27 is the current release.

Answer 4

Not 100% sure if this will work, but you can use the jvmRoute attribute, which is generally used in a load-balanced/clustered environment for the load balancers to be able to tell the nodes apart. Example:

<Engine name="Catalina" defaultHost="localhost" jvmRoute="node1">

This will end up generating a JSESSIONID value that looks like "ABCDEF123456.node1".
