It worked first, then I placed an order on my site

after the order is place

<CFSET STRUCTCLEAR(APPLICATION)>
<CFSET STRUCTCLEAR(SESSION)>
<CFLOOP INDEX="x" LIST="#GetClientVariablesList()#">
<CFSET DELETED = DELETECLIENTVARIABLE("#x#")>
</CFLOOP>
<CFCOOKIE NAME="cfid" EXPIRES="NOW">
<CFCOOKIE NAME="cftoken" EXPIRES="NOW">
<CFCOOKIE NAME="cfglobals" EXPIRES="NOW">

I do that and boom.... thats all she wrote application.cfc won't run again to restablish all.
