Defined in:

Overview

Resolves an incoming (locale, path) that 404'd against SiteMap URL history
and returns the page's current path so the caller can serve a 301.

This is the request-time half of the self-healing-rename design — see
doc/tasks/202606042115_SITEMAP_URL_HISTORY.md. When the sitemap generator
renames a page it records the old path in SiteMapPathHistory; a later request
to that old URL lands here (via Controllers::ErrorRendering#render_404) and is
301'd to the page's current path.

no history match (or redirecting would be unsafe).

  • path (String) —

    the locale-stripped request path, e.g. "/radiant-panel/ember/flex"

    the page's current locale-less path, or nil if there's
    no history match (or redirecting would be unsafe)
