Repost: T3: Stop back button view of a form

[James Sherwood <js...@rgisolutions.com>]

Hello,

I was told I posted this in the wrong spot so I am sending to the list again and hopefully it goes in the right spot..

I am trying to stop users from submitting a form and then pressing the back button and seeing the form again.  I would like to either redirect them somehow or just show them a session expired.

Any ideas?

Thanks,
--James

Lance,

Thanks, That is actually what we are trying right now.

We are taking the route of an onload where it just checks a service(or maybe 
a cookie we havent nailed that down) to see if they have submitted and just 
does a redirect if they have.

Ok, here's a solution... use an onload script to either
a) populate a zone with the form fields
b) populate the zone with an already submitted message
This way the form will not be in the browser's cache.

If you want to redirect you'll need to use javascript since it'll be an ajax
request.

Cheers,
Lance.

Not really possible I'm sorry, when a user hits the back button, the page
they are viewing is in their browser cache (ie not a serverside hit).
Probably the best solution is to set a flag (persistant property or in the
db) on first form submit then fail any subsequent submits by redirecting to
an error page.

Cheers,
Lance.
