摘要： On a mobile communications device, visiting a link from a messaging application or web browser may result in an undesired action, such as visiting a phishing site, downloading malware, causing unwanted charges, using too much battery, or the device being exploited. In an implementation, a mobile application intercepts a request including an identifier associated with an action to be performed by another application on the device and evaluates the identifier to determine when the request should be permitted, blocked, or conditionally permitted. The client may use local data or make a request to a server to evaluate the identifier. In an implementation, server communications are optimized to minimize latency by caching evaluation results on the device, proactively priming the device's DNS cache, optimizing when DNS lookups are performed, and adapting evaluation policy based on factors such as the source of the request, and the currently active network connection.

摘要： Client and user activity in an application or a browser are monitored to determine whether potential actions will result in a server being contacted. A DNS request to resolve the server's host name is generated to ensure the server's IP address is cached and available.

摘要： When a mobile device interacts with a network service, synchronous DNS resolution can significantly impact user experience due to lossy or moderate-high latency conditions. Network services that rely on low-TTL DNS records for failover require a client to frequently resolve the service's host name. It is undesirable to block on these frequent resolutions. In an implementation, user activity on a mobile device is monitored to determine whether the user is engaged in an activity that would contact a server. If such an activity is in progress, then DNS requests to resolve the server's host name are periodically generated to make sure the server's IP address is cached. In an implementation, if a request to communicate with a server fails, the DNS cache expires the entry for that server so that a new DNS request can resolve the server's IP address in case the server's IP address has changed.
摘要翻译： 当移动设备与网络服务进行交互时，由于有损或中等 - 高延迟条件，同步DNS解析可能会显着影响用户体验。 依靠低TTL DNS记录进行故障切换的网络服务需要客户端来频繁地解析服务的主机名。 阻止这些频繁的分辨率是不希望的。 在实现中，监视移动设备上的用户活动以确定用户是否参与将与服务器联系的活动。 如果此类活动正在进行中，则会定期生成解析服务器主机名的DNS请求，以确保服务器的IP地址已被缓存。 在一个实现中，如果与服务器通信的请求失败，则DNS缓存会超时该服务器的条目，以便新的DNS请求可以解析服务器的IP地址，以防服务器的IP地址发生更改。
