OK, so if you're wanting to change the URL that the client is retrieving, you need to use an HTTP redirect (return a django.http.HttpResponseRedirect() class from your view). This sends the new URL to retrieve back to the client, which then requests the new URL and gets the new page. Hopefully your URLs contain enough information on their own to describe what data is displayed on the page, because an HTTP redirect is just the URL that should be retrieved. Remember that the client's browser's URL line isn't just a visual thing. It has real semantics. It shows the resource they requested, so it only changes when they request a different resource. Have a look at django.contrib.auth.views.redirect_to_login() if you want an example of how to build a semi-complex URL for redirecting. There are also examples of using redirects scattered through the documentation, particularly in the forms documentation.
