How do you mean "unable"? That's not a very good problem description.

RESPONSE.redirect is simply a Python method, and it will take any string 
you can manage, no matter where it comes from. In fact, I think it would 
be very difficult to do otherwise.

You must, of course, pass the value of a variable, and not the variable 
itself. None of the following pose any problem::

  REQUEST.RESPONSE.redirect("http://plone.org")

  url = "http://plone.org"
  REQUEST.RESPONSE.redirect(url)

  def redir():
    return "http://plone.org"
  REQUEST.RESPONSE.redirect(redir())

  urls = {}
  urls['plone'] = "http://plone.org"
  REQUEST.RESPONSE.redirect(urls['plone'])

  REQUEST.RESPONSE.redirect(urls.get('plone', "/"))

In fact, they should all work identically.
