    摘要: A read is aligned to a reference data set. It is determined whether the read includes any identifier distinction, the determination being performed using the alignment. If so, positional data corresponding to the identifier distinction(s) are defined. Compressed read data is stored in association with a read identifier of the read. The compressed read data includes alignment information (e.g., a start and/or stop position of the alignment). When the read includes an identifier distinction, the compressed read data further includes the positional data and deviation data characterizing the distinction.

    摘要: A server computer queries a client device using a test fingerprint that does not correspond to any document stored in the client device, and restricts access by the client device to the server computer if the query result is incorrect. In some implementations, the server selects a set of first fingerprints associated with documents stored in the client device, generates a set of test fingerprints, none of which are associated with any document stored in the client device, and queries the client device using fingerprints from the set of first fingerprints and the set of test fingerprints to produce query results. The server computer restricts access by the client device to the server computer if at least one of the query results is incorrect, and enables the client device to access the server computer if at least a predefined number of the query results are correct and none are incorrect.

    摘要: Before preloading a document to a client device, a server computer gets a client cache map associated with the client device. The client cache map has a matching entry for each document cached by the client device's cache. The server computer first checks if the document to be preloaded is already in the client device's cache by looking up the client cache map. If the document is cached, the server computer then checks whether the cached document's content is still fresh. As a result, the server computer preloads the document to the client device if the document is not cached or if the cached document's content is stale.

    摘要翻译: 在将文档预加载到客户端设备之前,服务器计算机获取与客户端设备相关联的客户端缓存映射。 客户端缓存映射对于由客户端设备的高速缓存缓存的每个文档具有匹配的条目。 服务器计算机首先检查客户机缓存映射中是否已经在客户端设备的缓存中预先载入的文档。 如果文档被缓存,则服务器计算机然后检查缓存的文档的内容是否仍然是新鲜的。 因此,如果文档未被缓存或缓存的文档内容过时,服务器计算机会将文档预加载到客户端设备。

    摘要: A server computer identifies a cached document and its associated cache update history in response to a request or in anticipation of a request from a client computer. The server computer analyzes the document's cache update history to determine if the cached document is de facto fresh. If the cached document is de facto fresh, the server computer then transmits the cached document to the client computer. Independently, the server computer also fetches an instance of the document from another source like a web host and updates the document's cache update history using the fetched instance of the document.
