LookupCacheV4::Has implements safebrowsing v4 caching logic. 1. Check if fullhash match any prefix in local database: - If not, the URL is safe. 2. Check if prefix is in the cache(prefix is always the first 4-byte of the fullhash, Bug 1323953): - If not, send fullhash request 3. Check if fullhash is in the positive cache: - If fullhash is found and it is not expired, the URL is not safe. - If fullhash is found and it is expired, send fullhash request. 4. If fullhash is not found, check negative cache expired time: - If negative cache time is not expired, the URL is safe. - If negative cache time is expired, send fullhash request.
