摘要： An application request router that routes incoming application message to various servers in a network farm, even though the original network request itself does not directly specify which server is to handle the request. The application request routing module uses intra-farm routing policy and characteristics of the request itself to identify which of the servers is to handle the message and then dispatches the message to the appropriate server. This allows a user to reconfigure the network farm by reconfiguring the capabilities of the servers in the network farm, and then altering the routing policy accordingly to take advantage of the reconfigured network farm capabilities.

摘要： The routing of requests in a shared hosting environment. The shared hosting environment includes a network farm of servers, each capable of processing the request corresponding to the host name. When a request is received, a router determines whether or not there is already a host name affinitization of subset of the servers to the host name corresponding to the request. If so, the message is dispatched to one of those affinitized servers. If not, one or more of the servers are affinitized to the host name to create a subset of affinitized server(s) for that host name. Different host names may have different subsets of servers that they are affinitized to. Over time, the affinitization may be terminated as appropriate.

摘要： Dynamically upsizing and/or downsizing a network farm in response to network demand. An application message router routes messages to the network farm. When the network farm approaches or is anticipated to be approaching capacity, a group of one or more servers may be added to the network farm. When the added server(s) are capable of participating in the network farm, the application message router is triggered to route also to the added servers. When the network farm has excess capacity, a group of one or more servers may be dropped from the network farm. This may be accomplished by triggering the application message router to no longer route messages to the removed servers. The removed servers may be either immediately or gracefully removed from service.

摘要： A caching system segments content into multiple, individually cacheable chunks cached by a cache server that caches partial content and serves byte range requests with low latency and fewer duplicate requests to an origin server. The system receives a request from a client for a byte range of a content resource. The system determines the chunks overlapped by the specified byte range and sends a byte range request to the origin server for the overlapped chunks not already stored in a cache. The system stores the bytes of received responses as chunks in the cache and responds to the received request using the chunks stored in the cache. The system serves subsequent requests that overlap with previously requested ranges of bytes from the already retrieved chunks in the cache and makes requests to the origin server only for those chunks that a client has not previously requested.

摘要： A load balancing system is described herein that proactively balances client requests among multiple destination servers using information about anticipated loads or events on each destination server to inform the load balancing decision. The system detects one or more upcoming events that will affect the performance and/or capacity for handling requests of a destination server. Upon detecting the event, the system informs the load balancer to drain connections around the time of the event. Next, the event occurs on the destination server, and the system detects when the event is complete. In response, the system informs the load balancer to restore connections to the destination server. In this way, the system is able to redirect clients to other available destination servers before the tasks occur. Thus, the load balancing system provides more efficient routing of client requests and improves responsiveness.
摘要翻译： 这里描述了一种负载平衡系统，它使用关于每个目的地服务器上的预期负载或事件的信息来主动平衡多个目的地服务器之间的客户端请求以通知负载平衡决定。 系统检测将影响目标服务器请求的性能和/或容量的一个或多个即将到来的事件。 在检测到事件时，系统通知负载平衡器在事件发生的时间内排除连接。 接下来，事件发生在目标服务器上，系统检测事件何时完成。 作为响应，系统通知负载均衡器恢复与目标服务器的连接。 这样，在任务发生之前，系统能够将客户端重定向到其他可用的目标服务器。 因此，负载平衡系统提供更有效的客户端请求路由并提高响应能力。

摘要： An intelligent caching system is described herein that intelligently consolidates the name-value pairs in content requests containing query strings so that only substantially non-redundant responses are cached, thereby saving cache proxy resources. The intelligent caching system determines which name-value pairs in the query string can affect the redundancy of the content response and which name-value pairs can be ignored. The intelligent caching system organically builds the list of relevant name-value pairs by relying on a custom response header or other indication from the content server. Thus, the intelligent caching system results in fewer requests to the content server as well as fewer objects in the cache.
摘要翻译： 本文描述了一种智能缓存系统，其智能地整合包含查询字符串的内容请求中的名称 - 值对，使得仅基本上非冗余的响应被缓存，从而节省缓存代理资源。 智能缓存系统确定查询字符串中哪些名称 - 值对可以影响内容响应的冗余，哪些名称 - 值对可以被忽略。 智能缓存系统通过依赖于内容服务器的自定义响应头或其他指示来有机地构建相关名称 - 值对的列表。 因此，智能缓存系统导致对内容服务器的请求减少以及缓存中的较少对象。

摘要翻译： 高速缓存系统将内容分成由高速缓存服务器缓存的多个单独可高速缓存的块，该高速缓存服务器缓存部分内容，并向原始服务器提供低延迟和较少重复请求的字节范围请求。 系统从客户端接收内容资源的字节范围的请求。 系统确定与指定字节范围重叠的块，并向原始服务器发送尚未存储在高速缓存中的重叠块的字节范围请求。 系统将接收到的响应的字节作为块存储在高速缓存中，并使用存储在高速缓存中的块来响应接收到的请求。 该系统提供与先前请求的字节范围重叠的后续请求，这些请求范围已经从高速缓存中检索到的块中，并且只向原始服务器请求客户端以前未请求的那些块。

摘要： Requests for content can be received from clients and forwarded to servers, and responses to the requests can be received from the servers and forwarded to the clients. A health model can also be maintained. The health model can be based on information in the responses and possibly also on information in the requests, and the health model can indicate the health of the servers in responding to different types of requests. The health model may differentiate between health in responding to requests with different features in URLs of the requests, such as different namespaces and/or different extensions.
