XML Templates and Redirects

Hi,

Looking to port a very simple ASP application to XML Templates. I
need to ability to search, receive user input, and update the DB. No
problem there, as it appears that I could use update grams or SPs, and
validate input via XSD.

My problem then is this: when a user enters some input, I want to
validate it and show a confirmation page prior to actually performing
the update. Is it possible to perform a redirect to the confirmation
page if validation is successful, or to use an alternate stylesheet in
the XML template at runtime.

Thanks
