Mobile main page contains <link rel="canonical" href="http://en.wikipedia.org/wiki/Main_Page" > - should be https too or at least protocol-relative.
Discussed in Sprint Planning: https://mingle.corp.wikimedia.org/projects/mobile/cards/417
The canonical link should be our "preferred" version of a given web page [1] and the one we want to encourage usage of - for example the one we want search engines to index. Since https is not mainstream http _should_ be the canonical link and this should not change across pages regardless of protocol or whether they are viewing via index.php. Do not make protocol relative as they are the same piece of content. [1] http://tools.ietf.org/html/rfc6596
