It is ineffective, as you do not use "topframe" later (in *this*
request).

The frameset and its frames parts are fetched in *different* requests.
The "REQUEST.set" only affects the REQUEST object for the
frameset. The REQUEST objects for the frame components are
not affected.

You have two options:

 * a session product (there are some around on zope.org)
   it allows you to save information across web requests

 * passing the additional information through a query string
   key=value pair (do not forget to "url_quote_plus")

see above.
