Subject RE: redirect paramter in the jk_workers file
Date Thu, 03 Sep 2009 05:54:20 GMT
Hi Rainer,

Yes , it support to the 1.29 mod jk.

But here issue is different, I am using the JDBC store for the clustering.

Suppose my application is running fine and that instant if node1 is goes
offline 

It need near about 10 - 20 sec to push the session in to DB and in between
these 10 sec I f I try to do anything in my application , the application
kick back me on login page.

To overcome from this login page issue I am thinking to use the redirect
parameter for two nodes.

In this case , can you please tell me wheather this is sutaible and how it
works.

Your mailer uses a very unfriendly way of formatting your messages. So I
do top posting.

Yes, as you can read on

http://tomcat.apache.org/connectors-doc/reference/workers.html

the atribute redirect is supported since version 1.2.9. For a two node
load balancer, you don't need it though. If you have many nodes in a
load balancer, the redirect expresses, which one you prefer for the
failover. If you dont specify it, the load balancer will use some other
working node according to its load values.

Regards,

Rainer
