[thelist] cf redirection

Why not write the message into the main page?

I adopted a technique used by jeff (and walker I think): session.pageresponse.
I'm sure it's used by a tonne of other people too. Actually, the pageresponse I
learnt from walker's original evolt.org code which used alot of cfincludes. But
due to the incompatability of cfinclude with setting cookies in some situations,
I shifted to using cflocation, which necessitated holding the pageresponse from
page to page - ie, using a session variable.

On every page, I have a placeholder for the response which looks something like
this (I usually put it in the header file I'm using, just above the content, and
colour it red to get attention):

	<cfif len(session.pageresponse)>
	<cfoutput><p class=response>#session.pageresponse#</p></cfoutput>
	<cfset session.pageresponse = "">
	</cfif>

In my Application.cfm:

	<cfparam name="session.pageresponse" default="">

And then to write to the pageresponse, eg, after a record has been deleted, or a
user has successfully registered, I'll use:

	<cfset session.pageresponse = "Thanks for registering!">
	<cflocation url = "index.cfm?#vars#">

By this method, the pageresponse is ready and waiting for whatever messages you
need to throw at the user - alerting them to required form fields, letting them
know that tasks have been completed successfully, or giving them specific
information in a step-by-step procedure.

I apologise if this is not the type of solution you were looking for, and you're
set on the timed-refresh.
