What happens if I click on a link while something is being prefetched?

When the user clicks on a link, or initiates any kind of page load, link prefetching will stop and any prefetch hints will be discarded. If a prefetched document is partially downloaded, then the partial document will still be stored in the cache provided the server sent an "Accept-Ranges: bytes" response header. This header is typically generated by webservers when serving up static content. When the user visits a prefetched document for real, the remaining portion of the document will be fetched using a HTTP byte-range request.
