Bases: urllib.request.HTTPRedirectHandler

HTTP redirect handler that validates redirect destinations.

redirect_request(req, fp, code, msg, headers, newurl)

Return a Request or None in response to a redirect.

This is called by the http_error_30x methods when a redirection response is received. If a redirection should take place, return a new Request to allow http_error_30x to perform the redirect. Otherwise, raise HTTPError if no-one else should try to handle this url. Return None if you can’t but another Handler might.
