ColdFusion Kinky eCards Update
Just fixed a small bug in my ColdFusion Kinky eCards Hayden Panettiere demo application. In the OnSessionStart(), I was clearing the session data. However, I was throwing the baby out with the bath water, so to speak, and was actually deleting the CFID and CFTOKEN as well. I am not sure if this was causing any bugs, per say, but I would definitely consider this to be a bad practice. Now, the new code, which can be downloaded from the Kinky eCards Project page has a modified OnSessionStart() event method that restores the CFID and CFTOKEN values after the SESSION scope is cleared:
<cffunction
name="OnSessionStart"
access="public"
returntype="void"
output="false"
hint="Initializes the user's session.">
<!--- Define the local scope. --->
<cfset var LOCAL = {} />
<!--- Store the use ID / TOKEN values before we clear. --->
<cfset LOCAL.CFID = SESSION.CFID />
<cfset LOCAL.CFTOKEN = SESSION.CFTOKEN />
<!---
Clear the session. We should do this incase we
are re-initializing.
--->
<cfset StructClear( SESSION ) />
<!--- Restore the ID/TOKEN values. --->
<cfset SESSION.CFID = LOCAL.CFID />
<cfset SESSION.CFTOKEN = LOCAL.CFTOKEN />
<!---
Set up a struct to hold the form data. We the need
the form data so that the user can go back and forth on
multi-page forms (ex. enter data and preview eCard).
--->
<cfset SESSION.FormData = {} />
<!--- Return out. --->
<cfreturn />
</cffunction>

Thanks for info. Excellent article...
Ben, great fix. Thanks a lot!
I'm new here and new to ColdFusion, but i'm a fan of ColdFusion too, thanks for the update, i'm reading the code line by line, hope can get some idea about eCard
Thanks
