The load balancing in a Java cluster is a feature of the underlying Java container and the connector used to connect it to a webserver. Or alternatively of the loadbalancer you use to distribute the load between the diffeent webservers. You didn't explicitly specify what you are using, so I will presume you are using several ColdFusion instances deployed on JRun, connected to a single webserver. The way you can influence to which server a request goes is through the jsessionid. Make sure you configure the cluster to use sticky sessions and then look up the server.id for each instance (in the connector.properties file in SERVER-INF). Any jsessionidof which the first 4 bytes are equal to the server.id will be directed to that instance. If you have a different setup, ask on the mailinglist for you loadbalancer vendor or Java container.

Alternatively, you could create multiple virtual servers in IIS, map each to one of those virtual servers, then break the connectors temporarily, then create the cluster, then map that to the "real" virtual server, then go back and fix the connectors manually so that you have two sets working at once.

Well, I'm wondering if I can access the instance using an external, website address. Our developers don't necessarily have access to logging into the server.

How do you get the session ids for each instance? What would the url look like that targeted a specific instance?

Being able to access the administrator in that manner implies that you've enabled the JRun built-in web server, of course. But if you've done that, you can use this to get to the apps on that instance as well, as long as both the built-in web server and the "real" web server use the same web root.

Re: Accessing Specific CF8 Instances
You can access the administrator for a particular instance using the internal JRun webserver port. If you want to get to your apps on a particular instance you'll have to manipulate cookies (assuming you're using sticky sessions) so that the session ID starts with the the correct prefix for the instance you want. -- WSS4CF - WS-Security framework for CF http://wss4cf.riaforge.org/ On 6 January 2011 08:13, Richard Steele wrote: > > Is there a way to access particular instances that are running on a load > balanced CF8 Enterprise server?

Accessing Specific CF8 Instances
Is there a way to access particular instances that are running on a load balanced CF8 Enterprise server? If so, how is that done? thanks in advance. ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:340488 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
