Subject RE: [users@httpd] [A2/Load balancing] mod_proxy vs. dedicated box?
Date Wed, 03 Sep 2008 09:32:16 GMT
Dedicated device = ??

What type of applications are running on server 1 & server 2? Sticky
sessions being used? Explain a little more of your configuration.

You should also be able to get a feeling for the distribution of the
requests by using balancer-manager
