Minor Feature Request : core/request : store redirected URLs

[sebilasse]

It could be useful to store all redirecting URLs in an array e. g. in the options object.
The options are returned with the response and the user now knows the URLs "in between" request and response.

It is worth investigating, in that browser caches are likely handling this automatically when a 301 or a 302 is provided. It might be totally unnecessary.
