Forum OpenACS Development: Using 'template::form create' to send form action and variables to another file

I'd like to use the templating api to redirect the form action to
another script file instead the original file that generates the form
itself (this is the default action). I've successfully used the -
action flag (template::form create <formname> -action <actionfile>)
to do this but I need access to the values entered into the original
form in the new script. I'm sure I can send them individually out as
hidden or url vars but does anyone know a better way that is
available within acs_templating? Thanks.
