4.1 http and https

The http scheme refers to the Hypertext Transfer Protocol. The url library supports HTTP version 1.1, specified in RFC 2616. Its default port is 80.

The https scheme is a secure version of http, with transmission via SSL. It is defined in RFC 2069, and its default port is 443. When using https, the url library performs SSL encryption via the ssl library, by forcing the ssl gateway method to be used. See Gateways in general.

— User Option: url-honor-refresh-requests

If this option is non-nil (the default), the url library honors the HTTP ‘Refresh’ header, which is used by servers to direct clients to reload documents from the same URL or a or different one. If the value is nil, the ‘Refresh’ header is ignored; any other value means to ask the user on each request.
