I am submitting you a post I did before to a similar question. Kinda big
but there. CFLOCATION works wonders here. It sends you to your form again
without any form variables, thus removing the need to refresh. Of course
the URL needs to be adjusted for your use but the one I put here works OK
with no URL variables.
--------------------
If you are about to deploy, I would not do it. There are issues when
introducing no chache-ing in your pages that you would need to solve. The
one that gave me more problems is back/forward buttons in the user browser.
Imagine this
1. Form a.cfm
<cfform action="b.cfm">
<input type=text name="foo" value="var">
<input type=button name="submit">
</cfform>
2. Form b.cfm
<cfquery name="xxx" datasource="yyy">
insert into aTable (aField) values ('#FORM.foo#')
</cfquery>
Thanks for your input. To continue
<a href="c.cfm">go here</a>
3. Form c.cfm
<BODY>
Just nothing.
</BODY>
This is the deal: If you go from a, to b, to c, and then press the back
button to b.cfm you get a problem. This is a copy/paste from IE:
-----
Warning: Page has Expired The page you requested was created using
information you submitted in a form. This page is no longer available. As a
security precaution, Internet Explorer does not automatically resubmit your
information for you.
To resubmit your information and view this Web page, click the Refresh
button
-----
If you press refresh, then you get a double insertion.
This is how I get rid of the problem in a browser friendly fashion. Get
b.cfm as follows (check the uppercase)
<CFIF ISDEFINED("FORM.FOO")>
<cfquery name="xxx" datasource="yyy">
insert into aTable (aField) values ('#FORM.foo#')
</cfquery>
<CFLOCATION ADDTOKEN="NO" URL="#getFileFromPath(getBaseTemplatePath())#">
</CFIF>
Thanks for your input. To continue
<a href="c.cfm">go here</a>
etc, etc.
