1/**
2 * Fixes the "broken page on Back" issue across the system and public sites.
3 *
4 * Many forms (contact, registration, purchase) render their result inline on a
5 * POST response instead of redirecting. When the user later navigates Back to
6 * such a page the browser tries to re-display the stored POST response, which
7 * shows a broken / expired page. Pages restored from the back/forward cache
8 * (bfcache) can also come back with stale, non-functional JS state.
9 *
10 * On any back/forward navigation (or a bfcache restore) we re-fetch the page
11 * with a clean GET via location.replace(), so Back always lands on a freshly
12 * rendered, working page. replace() (not reload()) avoids re-issuing the
13 * original POST and keeps history clean.
