摘要： Disaster Recovery (DR) and High-Availability (HA) are a critical features required by many information technology systems. DR and HA may be accomplished with a remote secondary site that is kept synchronized with a primary site. To reduce the cost of maintaining a secondary site, the data may be split into two subsets wherein only a first subset of data is kept synchronized at the secondary site using a small bandwidth communication link. The second set of data, which is generally much larger, is periodically backed up at a network accessible back-up location. When a disaster occurs, the secondary site may access the most recent back-up of the second set of data. In a maintenance or limited failure situation, the secondary site can directly access the second data set at the primary site.

摘要： The special handling of multiple identical requests for the content during content caching is disclosed. A request for content, such as a web page request received from a client, is received. At least one of two actions is then performed. First, in response to determining that the content is cacheable and that a previous request for the content has already been forwarded to a server responsible for the content, such as a web server, the request is not processed until a response to the previous request is received. Second, in response to determining that the content is non-cacheable, the request is forwarded to the server responsible for the content.
