title: ColdFusion application seems to favor one node of cluster
body: <p>We have a number of Coldfusion applications (CF 9, multiserver on Linux) which run on a pair of servers front-ended by a pair of Apache web servers. It seems that 90% of the traffic is going to the first CF node. We've used dynatrace to track this and both the number of sessions and the time spent on both nodes are etremly skewed. It does seem too that a large percentage of the time spent on node 1 is spent in database copmmunications (Oracle) but node 2 shows hardly any database activity.</p>
  
  <p>Are there any general reccommedations on coding applications for a coldfusion cluster or any other ways to diagnose the problem?</p>
  
  <p><strong>Edit 1</strong></p>
  
  <p>The flow as I understand it is:</p>
  
  <p>F5 load balancer -> web server (where siteminder validates authorization) -> CF</p>
  
  <p><strong>Edit 2</strong></p>
  
  <p>From the CF side, the cluster is set up with round robin scheduling and both sticky sessions and replicate sessions enabled.</p>
