Clearing your session variables!
A question I get quite often is:
What is the best way to "kill" all sessions in my
ColdFusion application?
Well, my answer always is.... It just takes 3 lines of code (Don't you just love ColdFusion? ;)
<cfscript>
StructClear(Session);
</cfscript>
The command above will instruct ColdFusion to "kill" all sessions for the current client.
