/**
 * Fetch a resource from remote or local cache.
 *
 * When using this function, we first check if the resource is available in the local cache
 * by using the page url as the cache key prefix.
 *
 * If none is found, we fetch the page from the remote server and cache it locally,
 * then return its content.
 *
 * If the local cache includes a potential match, we make a `HEAD` request to the remote server
 * and compare the ETag with the one stored in the local cache.
 *
 * If the ETag matches, we return the cached content. If it doesn't match,
 * we fetch the entire page using a `GET` request and update the local cache with the new content.
 *
 * @param props - options for fetching a resource
 * @param props.url - the URL of the resource to fetch
