Note: Some HTTP redirections require action from this module's client code. If this is the case, HTTPError is raised. See RFC 2616 for details of the precise meanings of the various redirection codes.
Nonein response to a redirect. This is called by the default implementations of the
http_error_30x()methods when a redirection is received from the server. If a redirection should take place, return a new Request to allow
http_error_30x()to perform the redirect. Otherwise, raise HTTPError if no other Handler should try to handle this URL, or return
Noneif you can't but another Handler might.
Note: The default implementation of this method does not strictly follow RFC 2616: it allows automatic 302 redirection of POST requests, because essentially all HTTP clients do this.
Location:URL. This method is called by the parent OpenerDirector when getting an HTTP `moved permanently' response.
