Hello,
your solution:

class toSite(object):
    def __call__(self):
        from zope.app.zapi import *
        site = getSite()
        defaultViewName = getDefaultViewName(site, self.request, site)
        view = getMultiAdapter((site, self.request), name=defaultViewName)
        return view()

get the same results as mine:

class toSite(object):
    def __call__(self):
        from zope.app.zapi import absoluteURL
        URL = absoluteURL(getSite(), self.request)
        return self.request.response.redirect(URL)


What are the differences? Which is better? Why?

I think yours is better since it does not involve a redirect. What do you 
think?

Thanks,

Florian
