    摘要: When requested content is available at a data center, the data center returns the requested content to the data center. When the requested content is locally unavailable at the data center, the requested content is retrieved from an origin server. The retrieval of the content from the origin server may be delayed based on the processing load at the origin server. When retrieval of the content is delayed, the request is prioritized and placed in a queue for handling by the origin server based on the priority of the request. Also, when retrieval of the content is delayed, a status page may be communicated to the browser to inform a user of the delay and provide alternate content and status information related to the request determined as a function of the request or the current state of the origin server.

    摘要: A data center determines whether requested content is available at the data center. The content is available when the content is both present at the data center and current. When the requested content is available at the data center, the data center returns the requested content to the browser. When the requested content is locally unavailable at the data center, the requested content is retrieved from an origin server. When retrieval of the content is delayed, the request is prioritized and placed in a queue for handling by the origin server based on the priority of the request. A status page may be communicated to the browser to inform a user of the delay and provide alternate content and status information related to the request determined as a function of the request or the current state of the origin server.

    摘要: A data center (14) receives a request (22) for content from a browser (12) on a client (11). The data center determines whether the requested content is available at the data center. The content is available when the content is both present at the data center and current. The content may be expired and marked as non-available in response to an expiration command (24). When the requested content is available at the data center, the data center returns the requested content to the data center. When the requested content is locally unavailable at the data center, the requested content is retrieved from an origin server (18). The retrieval of the content from the origin server may be delayed based on the processing load at the origin server. When retrieval of the content is delayed, the request is prioritized and placed in a queue for handling by the origin server based on the priority of the request. Also, when retrieval of the content is delayed, a status page may be communicated to the browser to inform a user of the delay and provide alternate content (139) and status information related to the request determined as a function of the request or the current state of the origin server.

    摘要: A cache server (18) may prefetch one or more web pages (30) from an origin server (16) prior to those web pages being requested by a user (13). The cache server determines which web pages to prefetch based on a graph (42) associated with a prefetch module (40) associated with the cache server. The graph represents all or a portion of the web pages at the origin server using one or more nodes (130) and one or more links (100) connecting the nodes. Each link has an associated transaction weight (102) and user weight (104). The transaction weight represents the importance of the link and associated web page to the origin server and may be used to control the prefetching of web pages by the cache server. The user weight may be used to change a priority (46) associated with a request (22) for a web page. The user weight and transaction weight may change based on criteria (50) associated with the origin server.

    摘要翻译: 缓存服务器(18)可以在用户(13)请求的那些网页之前从原始服务器(16)预取一个或多个网页(30)。 缓存服务器基于与与高速缓存服务器相关联的预取模块(40)相关联的图形(42)来确定要预取哪些网页。 该图表示使用一个或多个节点(130)和连接节点的一个或多个链路(100)的原始服务器上的网页的全部或一部分。 每个链路具有关联的事务权重(102)和用户权重(104)。 交易权重表示链接和关联网页对原始服务器的重要性,可用于控制缓存服务器对网页的预取。 用户权重可以用于改变与网页的请求(22)相关联的优先级(46)。 用户权重和交易权重可以基于与原始服务器相关联的条件(50)而改变。
