There are a couple ways to accomplish this.
In order for this to work, the page prior to the page which is
expiring needs to move to the page that's expiring using an http get
operation... so for instance,
1. form
-post-
2. form action <--+ expired
-link- |
3. other page |
-back button-----+
To make this work so that the form result page doesn't expire, you
have to change the method attribute of the form tag to get instead of
post... Unfortunately this still carries the issue of users
resubmitting the form by hitting the refresh button.
There is another way to make this work that's slightly more
complicated, but which also solves the form resubmittal problem and
allows you to maintain the post action of the form...
1. form
-post-
2. form action
-cflocation-
3. result page <--+ not expired
-link- |
4. other page |
-back button-----+
The cflocation can move to a page that uses session variables or
_preferably_ url variables (since they won't expire) to get the
information relevant to the form post action. Since the visitor won't
see the form action page (it's replaced in the browser's history
stack) the experience is transparent to them.
