I have inherited an application that makes fairly extensive use of CLIENT variables (nothing complex, just simple user preferences in a multi-server environment), but poorly manages them. I have been tasked with the cleanup and maintenance of them, and I have a couple of questions regarding CLIENT variables in general.
1. Because I have several CLIENT variables which are used in many places throughout the application (several meaning about 7, but more could come with future enhancements), would management be easier if I retrieved all the CLIENT variables associated with that particular user when they log in and throw them into a structure? Better yet, would I be better off storing the variables as a structure to begin with by using WDDX? 2. We have had several instances of two people at entirely different companies and locations overwriting each other's client variables. For example, if a user logs in, the home page will say "Welcome Back, Dave Carabetta." However, what happens on occasion is that if the user clicks a link on the home page, the new page loads, but it will now say "Welcome Back, John Smith." This situation is not consistent, and we haven't been able to replicate it. Yet our customers call in and it's really happening. Any ideas? 3. In connection with the above problem, every now and then, when the page loads, instead of saying "Welcome Back, Dave Carabetta," it will say "Welcome Back, 523175 523175." After extensive research, it turns out that 523175 is the value of my CFID. Upon refreshing the page, my name appears again as it should. Again, not consistent, yet it happens. There are grumblings around here that CLIENT variables are not a viable solution for our site, which I disagree with completely. But I don't have any proof right now that it's our implementation versus the underlying technology. Any more ideas? 4. I have seen the recommendation to change the CFID value from the default number to a global UUID. We are using CF on Solaris. Where is the "registry" entry that would need to be changed so that the new long UUID is used instead of the incrementing number? 5. If a user logs in using IE, and then logs in using Nutscrape or another browser, will they have two different sets of user preferences in the CDATA and CGLOBAL tables in the database? I assume they will because the browsers use their own cookies, but I just wanted to confirm this. I think that's it. Thanks in advance for any and all help.
