[ZPT] Pass parameters via RESPONSE.redirect

[Rainer Thaden]

Hi,

i'd like to present a list of objects on a site and the user should
have the option to change the parameters which define the list (e.g.
display all obj from a certain author). On top of the site there's a
form which passes the parameters to a script (author='bla') and the
script redirects to that page.
Looks like this:

<form>: author -> select box
        action -> script, which gets authorname
</form>
<div tal:define="author request/author | python:'Mad Max'">
list items
</div>

How do i pass the parameters given to the script to the page via the redirect?
When i try to add the author to the request in the script like
request.set('author',author)
it doesn't show up in the request in the redirected page.

In DTML there's something like passing keyword arguments to a response
page which show up in request/options.
Is there something similar in ZPT?
