Yes. But I don't necessarily see the value of using Application variables at all in this example. You could just as easily set a page or Request variable in onRequestStart, and override it as needed on individual pages. The value of using Application variables really comes from one or the other of these two use cases: 1. It's expensive to create the variable. That doesn't appear to be the case here. 2. The value of the variable will change over the life of the application. While that's true on its face here, as some pages will have one value and other pages will have another, that's not really a match for the use case, as these changes don't happen over the life of the application - they're just different values for different pages.
