In preparation for the eventual deployment of full HTTPS support on Stack Exchange, and also to make the currently available "alpha" HTTPS support more usable, all links from Stack Exchange sites to other Stack Exchange sites should be protocol-relative.
Currently, at least the following places still feature links with explicit
http: protocol prefixes:
- the page footer,
- the "Hot Network Questions" and "Community Bulletin" modules in the sidebar,
- the "inbox" and "achievements" menus in the top bar (the site switcher menu is OK, though),
and, of course,
- lots and lots of user-supplied links in post and comment content.
I've posted this feature request with the intent to provide a single central place for tracking these issues, rather than having them scattered across multiple meta threads. If you find more places on SE where protocol-relative links should be used, please report them below.
I fully expect this request, in its full sense, to be treated as status-deferred for the time being; however, these issues do need to be fixed at some point before our HTTPS support is ready for "prime time".
Ps. Yes, the next release of SOUP (v1.10) is going to include a general client-side fix for most of these issues. In the mean time, the HTTPS Everywhere plugin effectively provides the same functionality, and much more besides.
