Clearly, the jvmRoute must uniquely identify each TC instance in a cluster.
The fact that it is an 'attribute' of the Engine object means that it may be
specified in server.xml (as an attribute of the Engine tag). However,
there is no reason it couldn't be assigned in a different, more automatic,

is 'difficult' to set SO_TIMEOUT on a URLConnection. Actually,
it's impossible, unless you provide your own URLStreamHandler.
And this requires that you start reading sun's java.net source code.

I'm not a tomcat developer (yet), but, I've been writing code that provides
fail-over capability by providing distributed (cluster) session managment.
My review of the catalina code indicates that org.apache.catalina.Cluster is
not currently useful. The distributed session store does not '
instance the 'owner' of the session. All other repositories are updated
with this change.
- tc Manager updates it's local session cache.
- tc sends response (contains session id)
- tc sends updated session to cluster repository (and unlocks session)
- Apache sends response to client

Should this routing id be an attribute of the one of the Container

store this mapping (of session id to owner vm) in a hashtable.
Then, in subsequent requests, do a hashtable lookup to find
the owner vm. Solutions that require a large routing table
are probably not desirable, but would probably result in the
greatest flexibility.

Thanks for your very informative reply. From your reply, it seems
that mod_jk comes close to doing what I want, and should actually
provide the fail-over I'm looking for, however not in the most
optimal way.
What would be involved in adding (optionally configured) logic to
mod_jk that w
the given JSESSIONID.
Second question: How can I go about getting the
necessary connector level changes made that will
support re-routing of requests for sessions hosted
on a 'downed' tomcat to some other tomcat?
This re-routing of requests is critical. Without it
fail-over is simpl
l only be present (and consume bandwidth) if it has been
configured. Other load balancing solutions that don't require fail-over
protection, such as the Tomcat 3.x / Apache solution can be implemented
without concern for this.

In short, the distributed session management feature is nearing completion.
I'm creating pretty comprehensive JUnit tests along with this code, so my

Mika, Costin:
While pondering things yesterday, the thought occured to me as well,
perhaps this whole notion of distributed management had a wider
application (beyond simply HttpSessions).
Having said that. I disagree, that Tomcat should expose an 'object
replication service' api to web-applicat
n the
org.apache.cluster package.
I should have something to share in the next couple of
days. I'll be creating JUnit tests as I write this code. Is there
a standard place to put JUnit tests, or can I simply place
them in the same package as the classes being tested?
