GitBlit doesn't use SNI when accessing https urls

[silid]

I'm trying out Gitblit federation. The origin server is behind an SSL proxy that uses SNI to redirect to different hosts. This works fine in the browser, but the pulling Gitblit server doesn't send the SNI and so SSL handshake fails.

Federation does work when accessing the machine directly, but as federation uses the web.canonicalUrl setting, this needs changing and it is then wrong in the shortcuts for the users.
