RE: stop reposting of form data
Sounds like you are agreeing with me. By using CFLOCATION you are causing another round-trip from the server to the client back to the server and back to the client again.

RE: stop reposting of form data
Fusebox does do that... You simply make the form action piont to an action fuse, (act_xxx_post or something) and then cfinclude the action template and then cflocation to a success page or anywhere else.. -Original Message- From: Peter Theobald [mailto:[EMAIL PROTECTED]] Sent: Saturday, January 20, 2001 1:35 AM To: CF-Talk Subject: Re: stop reposting of form data I think this is how Fusebox gets around the problem of having all requests go to the same page (index.cfm) (dont quote me on that...

I use session variables. For example: ...various form stuff... ...SQL, logic and so on... Obviously, you need to lock those session variables or Duplicate() them into the request scope, but that's the basic idea. -- Roger ~~ Structure your ColdFusion code with Fusebox.

RE: stop reposting of form data
Now that is an interesting little trick. I think I will try that one. The only way I could figure out how to do it was to query the bd first to see if there was a record matching the info from the form and then do the cflocation if a match was found, which would cause a performance decrease.

You should prevent this both on the client side (for a nicer interface) and on the server side (in case scripting is turned off, or a hacker wants to mess with you by submitting his own form to your scripts) Server side: Have a hidden field set to a random string (use CreateUUID) and save that "transactionID" in the database.

Re: stop reposting of form data
I think this is how Fusebox gets around the problem of having all requests go to the same page (index.cfm) (dont quote me on that... I dont know much about Fusebox...)
