RedirectCache — use Interchange to generate static web server pages
This directive, along with AcceptRedirect, allows
the web server to route requests for missing static HTML pages to Interchange.
Interchange processes the requests and saves the produced static content
to the directory pointed by RedirectCache. On next web server
page access, the pages are found and served as static content by the
web server directly.
Requests routed to Interchange in this way use a temporary session (mv_tmp_session).
In case the Interchange page is not found, the usual SpecialPage "missing"
is shown and no writing to the web server HTML directory takes place.
