If ColdFusion is Still Your Thing...

Found a simple way to prevent form resubmission from page refresh and back button.

Here's how I have mine set up:

• Enable sessionManagement on Application.cfm
• Seperate form, action, and completion pages

then add this line on the top of the action handler cfm (insert,delete, etc)

<cfif structKeyExists(session, "submittedAlready")>
    <cfset structDelete(session, "submittedAlready")>
    <cflocation url="index.cfm" addtoken="false">
<cfelse>
    <cfset session.submittedAlready = "true">
</cfif>

Done! No resubmission.

FYI, I'm no expert in ColdFusion. Just wanted to share this with all the newbies out there like myself.
