Nitro's cached handler renders from a header-less copy of the request, so under swr route rules useJournalApi, /rss.xml and the sitemap source forwarded only the Nuxt peer and every cache miss shared one Journal API rate-limit bucket (deferred in Phase 16). A Nitro plugin records x-forwarded-for plus the peer in event.context.journalForwardedFor on the request hook; the three callers forward it. Same key as the host app's workaround, which keeps working. The acme SSR smoke's x-forwarded-for check on the now route-cached playground is the test.

// The Journal API client for pages and components. On the server it calls

// server, also on route-cached renders. In the browser it calls the same-origin public base. The base is
