Ouch, I need to retract the above incorrect claims :-(

REQUEST.set modifies the current request. It is nothing more than a
singleton <dtml-let>. It sets variables within the page itself, and it
has no influence on next pages.

To carry variables from one page to another, you need to use
CoreSessionTracking product or other session tracking products. You can
also choose to use hidden form variables in cases where it does not
present a security risk.
