 Fastly domain purges invalidate the entire configured service. Use one domain per Fastly service when calling `purgeDomain()`. Cloudflare hostname purging depends on the cache-purge features enabled for your plan.
 
-### Cache routing
-
-`Cache\Adapter\Proxy` routes domain and path purges: it sends the application domain to one adapter, configured network domains to another, and fans custom domains out to every custom adapter.
-
-```php
-use Utopia\Cdn\Cache\Adapter\Proxy;
-
-$cache = new Cache(new Proxy(
-    appDomain: 'app.example.com',
-    appDomainAdapter: $cloudflareCache,
-    networkAdapter: $fastlyCache,
-    customDomainAdapters: [$cloudflareCache, $fastlyCache],
-    networkDomains: ['network.example.com'],
-));
-```
-
-Cache keys and tags are scoped to a Fastly service or Cloudflare zone. Consequently, `Proxy` does not route `purgeKeys()` calls. The consuming application must select the adapter using its own routing context before constructing `Cache`:
-
-```php
-$adapter = $cdnAdapterResolver->resolve($rule);
-
-$cache = new Cache($adapter);
-$cache->purgeKeys([
-    'domain-' . \strtolower($domain),
-]);
-```

 ## Certificates
 
 The current certificate provider support is focused on CDN-managed certificates through Fastly TLS subscriptions.
