Hi Ryan,
1) I hope you know that client variables aren't really stored on the client
(unless you are implementing them as cookies)
2) There is a special client variable called "Client.LastVisit" which
generally exists (I think there is some setting in CF Admin to turn them
on/off, but I forgot where. Then use some code like this:
IF THE USER HAS NOT VISITED THE PAGE IN MORE THAN 20 MINUTES, PURGE
SPECIFIC CLIENT VARIABLES
<CFSET PurgeClientVarList = "UserID,MemberID,ShopptingCartList,Preferences">
<!--- IF THE USER HAS NOT VISITED THE PAGE IN MORE THAN 20 MINUTES --->
<CFIF DateDiff('n',Now(),Client.LastVisit) GT 20>
<CFLOOP list="#PurgeClientVarList#" index="CurVar">
<!--- TO MAKE IT NON-EXISTANT --->
<CFSET Temp = DeleteClientVariable(CurVar)>
<!--- OR IF YOU WANT IT TO EXIST BUT BE EMPTY --->
<CFSET Client.#CurVar# = "">
</cfloop>
</cfif>
Cheers,
