Q&A

Q1:Because ColdFusion's client-state management uses cookies, how is it any better than other cookie-driven Web tools?
A1: There are several Web tools that support cookies, but in most cases these tools store all of a user's collected data in the cookie. ColdFusion stores the user data on the server and uses the cookie only for identification. This has benefits both in security and in speed.
Q2:Because my users never actually look at my Application.cfmpage, how do my other templates get information from it?
A2: A good way to think of Application.cfm is as an "included" file on each of your templates. Any variable definitions or parameters that appear in Application.cfm are implicitly added to the beginning of each of your templates as users view them.
Q3:My client runs a clustered server setup. Won't this cause problems if user data is saved to an individual system's registry?
A3: Yes, and the solution is to use a central database to store user information. This is done with either the CLIENTSTORAGE parameter in Application.cfm or the "variables" link in ColdFusion Administrator.
Q4:How secure are cookies sent using the SECUREparameter?
A4: As secure as Web pages that use this feature. SSL has become a fairly well-respected method for sending secure data.
