That is a common misconception. By default, when you install the web server connector, it creates a wildcard mapping as Jochem mentioned. This allows JRun/CF to process generic servlet requests, which have no file extension. By default, also, the default context root is "/", which of course is common to every request. So, when someone requests a static file, the connector forwards the request to JRun, which quickly determines that it's a static file and returns that request to the web server for processing. (At least, that's my understanding of how the process works; I could very well be wrong on some of the details.) > Per my original post, I have disabled sticky sessions and do > not intend to enable them.

I would not expect anything which depends on the creation of a file at runtime, to work by default in a non-sticky clustered environment. You should expect that you'll have to take special measures in those cases. In this particular case, you could use a different instance just for handling these requests; this instance would presumably be hooked to a separate web server instance, and would guarantee that requests that generate charts are only run from one place. Jochem may well have some better alternatives up his sleeve; I haven't read through the entire thread yet.
