- (bug 5519) Allow sidebar cache to be disabled; disable it by default.
- If on, the sidebar navigation links are cached for users with the
- current language set. This can save a touch of load on a busy site
- by shaving off extra message lookups. *
- However it is also fragile: changing the site configuration, or
- having a variable $wgArticlePath, can produce broken links that
- don't update as expected.
