I just thought of a way of doing this in one step, and it will work
globally for all fusebox applications!
You use the CF_LOCATION tag, instead of CFLOCATION, and set the online
cookie in one step. AND it should work with WHATEVER your default
FuseAction is in your index.cfm. AND it does not matter if you have
security turned on, or not, or whatever. It will always destroy their
client (or session vars, if you want) whenever they close their browser.
Put this code in a global location, say app_global.cfm.
===============================
<CFIF Not IsDefined("Cookie.Online")>
<CFLOOP LIST="#GetClientVariablesList ()#" index="curvar">
<CFSET temp=DeleteClientVariable(curvar) >
</cfloop>
<CFCOOKIE name="ONLINE" value="TRUE">
<CF_LOCATION url="index.cfm?fuseaction=main">
<!--- OR IF YOU WANT YOUR DEFAULT FUSEACTION, TRY THIS --->
<CF_LOCATION url="index.cfm">
</CFIF>
===============================
BTW, this code has the added side effect of forcing the user to come to the
main fuseaction (or whichever one you set) when they first come to the
site. ie, you can't open a link to any other fuseaction as the first page,
and expect it to work. This may or may not be desired.
I guess you could fix that like this, but you will need to run the code
after the <CF_URLFORM2ATTRIBUTES> tag:
<CF_LOCATION url="index.cfm?fuseaction=#attributes.fuseaction#">
