Ruby Mechanize retrieve headers

I'm using mechanize for web inspection, when I get a URL I get a refresh URL in the headers:

meta http-equiv="refresh" content="2;url=/html/Splash.action?splash="

When I ask to mechanize to list the metadata I do this:

pp $page.meta

I get:

Mechanize::Page::Meta
  ""
  "http://localhost/html/Splash.action?splash="

How can I cleanly retrieve the refresh URL?

Thanks

This works:

$page.meta.first.href

Either it's a bug in mechanize, or there's something wrong with the html, as it should have this is meta. BTW, Mechanize also has #follow_meta_refresh attribute, which is false by default.
