There is a method on REQUEST that does this already:

def resolve_url:
     # Attempt to resolve a url into an object in the Zope
     # namespace. The url must be a fully-qualified url. The
     # method will return the requested object if it is found
     # or raise the same HTTP error that would be raised in
     # the case of a real web request. If the passed in url
     # does not appear to describe an object in the system
     # namespace (e.g. the host, port or script name dont
     # match that of the current request), a ValueError will
     # be raised.
