What is the request scope for?
The request scope is a variable scope that has arisen from the development of Spectra. Spectra uses custom tags extensively. To avoid having to explicitly pass variables from one tag to another as attributes, the request scope was developed as a variable that is “visible” to all templates that are executed within one page request. Normally, custom tags operate within their own scope and do not have access to (cannot “see”) variables created in other tags. Request scope variables are visible to every tag called within one page’s execution. The other benefit is that if you use application variables for constants within an application, you should use cflock around all references to them, along with session and server variables. The request scope does not need to be cflocked and, as such, is ideal for storing contant values that are typically scoped as application values. So in your Application.
