[Zope] Virtual Host Monster does not work with the absolute_url()

Following the code of the standard "absolute_url" (to be found
in "OFS/Traversable"):

    def absolute_url(self, relative=0):
        try:
            req = self.REQUEST
        except AttributeError:
            req = {}
        rpp = req.get('VirtualRootPhysicalPath', ('',))
        spp = self.getPhysicalPath()
        i = 0
        for name in rpp[:len(spp)]:
            if spp[i] == name:
                i = i + 1
            else:
                break
        path = map(quote, spp[i:])
        if relative:
            # This is useful for physical path relative to a VirtualRoot
            return join(path, '/')
        return join([req['SERVER_URL']] + req._script + path, '/')

As you see, there are several possible reasons why you may get
the physical path:

  *  your object is unable to acquire "REQUEST" (because it is not
     (yet) acquisition wrapped)

  *  the 'VirtualRootPhysicalPath' in "REQUEST" is wrong (not very likely)

  *  the SERVER_URL or "_script" in "REQUEST" are wrong (not very likely)

  *  you happen to access a non-standard "absolute_url" (use, e.g. "DocFinder",
     to check that).
