For long lists of items, or where multiple renditions are used for each item, this can provide a significant boost to performance.

-Many websites use a frontend cache such as Varnish, Squid, Cloudflare or CloudFront to gain extra performance. The downside of using a frontend cache though is that they don't respond well to updating content and will often keep an old version of a page cached after it has been updated.
+Many websites use a frontend cache such as [Varnish](https://varnish-cache.org/), [Squid](http://www.squid-cache.org/), [Cloudflare](https://www.cloudflare.com/) or [CloudFront](https://aws.amazon.com/cloudfront/) to support high volumes of traffic with excellent response times.

 Wagtail supports being [integrated](frontend_cache_purging) with many CDNs, so it can inform them when a page changes, so the cache can be cleared immediately and users see the changes sooner.
 
 If you have multiple frontends configured (eg Cloudflare for one site, CloudFront for another), it's recommended to set the [`HOSTNAMES`](frontendcache_multiple_backends) key to the list of hostnames the backend can purge, to prevent unnecessary extra purge requests.

-## Caching proxy

-To support high volumes of traffic with excellent response times, we recommend a caching proxy. Both [Varnish](https://varnish-cache.org/) and [Squid](http://www.squid-cache.org/) have been tested in production. Hosted proxies like [Cloudflare](https://www.cloudflare.com/) should also work well.

-Wagtail supports automatic cache invalidation for Varnish/Squid. See [](frontend_cache_purging) for more information.

 ### Image attributes
 
 For some images, it may be beneficial to lazy load images, so the rest of the page can continue to load. It can be configured site-wide [](adding_default_attributes_to_images) or per-image [](image_tag_alt). For more details you can read about the [`loading='lazy'` attribute](https://developer.mozilla.org/en-US/docs/Web/Performance/Lazy_loading#images_and_iframes) and the [`'decoding='async'` attribute](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/img#attr-decoding) or this [web.dev article on lazy loading images](https://web.dev/lazy-loading-images/).
