What are the benefits of Layer0’s prefetching service worker over <link> tags with prefetch or HTTP Link headers?
<link rel="prefetch" href="/product-details.html" as="document">
These hints have limited browser support compared to service workers and only establish the connection but don’t prefetch response content like Layer0’s prefetcher does.
Layer0’s prefetcher is highly configurable. You can set it up to prefetch based on selectors, prefetch explicit URLs, prefetch only cache hits, throttle prefetch requests, and several other options.
