// Keeps the visitor's address available to route-cached SSR renders.

// An app rule such as `'/**': { swr }` renders cached pages from a copy of
|
|
// the request without headers. The SEO API throttles per client address,
|
|
// so forwarding only the Nuxt peer would put every cache miss in one bucket.
|
|
// The event context is shared with that copy, so the incoming
|
|
// x-forwarded-for plus the peer address is recorded here, before the cached
|
|
// handler runs, and resolveSeo and the 404 report forward it.
