Features

Feature	What you get
response-cache	Cache public GET 200 responses in KvStore.

Overview

When: cache public GET 200 responses (lists, marketing pages).

Does:

• Skips requests with Authorization / Cookie unless cache_private(true)
• Key = method + path + sorted Vary headers
• Sets X-Cache: HIT|MISS and Cache-Control
• Invalidate via ResponseCacheHandle::invalidate_prefix (e.g. from an EventBus listener)

Example

use std::sync::Arc;
use std::time::Duration;
use sova::{Memory, ResponseCache};

let store = Arc::new(Memory::new());
app.install(ResponseCache::new(store).ttl(Duration::from_secs(60)).vary(&["accept-language"]));

Notes

• Feature response-cache (+ store)
• Does not replace static file ETag — dynamic routes only

Quick start

use sova::store::Memory;
use sova::ResponseCache;
use std::sync::Arc;

app.install(ResponseCache::new(Arc::new(Memory::new())));
// From a handler / event listener:
// req.state::<ResponseCacheHandle>().invalidate_prefix("/api/notes").await;
