Summary

ColdFusion's Web Application Framework requires you to begin thinking of your templates as a whole. In doing so, you can design a site that shares common data between templates, uses default parameters, and saves user states between sessions. The keys to ColdFusion applications are configuration files called Application.cfm that reside in the upper-most folder of each of your application trees. In these files, you can set common variables for your applications and enable features such as client and session management.

Client-state management is ColdFusion's method for dealing with the statelessness of the Web. It gives you the ability to save user data between sessions and to read and write client variables that are specific to individual users. Session variables work in similar ways, although they only remain defined for as long as a user continues to browse your site.
