RE: ClusterCATS vs. hardware
Actually, using the getmetric() tag, we're able to have our load balancing hardware base it's load balancing off of the ColdFusion box's current load. We have our load balancer check a special page with nothing but the current running requests, and if the Running Requests are too high, it will send requests to the next available server. If ColdFusion isn't running (ie - no metrics coming back), the LB will send it to the next available server. We use a competitor to F5, but I'm pretty sure F5 can do the same thing.

OK, ClusterCats does one thing that hardware will never do - CF processing balancing ClusterCats will send requests to the least busy server for CF requests while hardware ones will only sent to ones which are still active (ping wise usually), also ClusterCats will determine if CF isn't running and won't send to there...

ClusterCATS vs. hardware
If I am using a hardware load balancing router (such as Cisco LoadDirector, or F5, or Alteon, etc), my application does not use Session variables, and my Client variables are stored in the database... Is there any benefit in using ClusterCATS in addition to my hardware load balancer? I already have users being directed to the server with the least load. I already have dead servers being taken out of rotation. --- Peter Theobald, Chief Technology Officer LiquidStreaming http://www.liquidstreaming.com [EMAIL PROTECTED] Phone 1.212.545.1232 x204 Fax 1.212.545.0938 To put this contact information into your Palm device, click here: http://www.coola.com/cgi-bin/addinfo.cgi?pid=15803&rid=972879910&type=A ~~ Structure your ColdFusion code with Fusebox.
