- qwiki-history-enabled? #!optional BOOLparameter
Controls whether to allow viewing of edit history, viewing and diffing of old revisions. These are all somewhat heavy operations which are (currently) uncached, so when server load is heavy it can be used to lighten the load a bit. Note that you'll have to delete the cached HTML files when toggling this parameter's value, as the "history" link on individual pages will be omitted when history is disabled and shown when it is enabled.
If the history URL is visited or a diff is requested, it leads to an ugly "forbidden" page. If a historical revision is requested, it will show the current revision (which is cached) unconditionally.
Defaults to #t.
