    Abstract: The invention allows to prevent robots from browsing a Web site beyond a welcome page. When an initial request from an undefined originator is received Web site responds to it with a welcome page including a challenge. Then, on receiving a further request from the undefined originator Web site can check whether the challenge is fulfilled or not. If fulfilled the undefined originator is assumed to be a human being and authorized to go on. If challenge is not however fulfilled the undefined originator is assumed to be a robot in which case site access is further denied. The invention prevent Web site contents from being investigated by robots while not requiring users to have to log on.

    Abstract translation: 本发明允许防止机器人在欢迎页面之外浏览网站。 当接收到来自未定义发起者的初始请求时，Web站点会响应包含挑战的欢迎页面。 然后，在收到来自未定义的发起者网站的进一步请求时，可以检查是否满足该挑战。 如果履行了未定义的发起人被认为是一个人，并被授权继续下去。 如果不满足挑战，则未定义的发起者被认为是机器人，在这种情况下，站点访问被进一步拒绝。 本发明防止网站内容被机器人调查，而不要求用户必须登录。

    Abstract: PROBLEM TO BE SOLVED: To facilitate the retrieval of an object while using a cache by sending back an object requested from another node among plural nodes by using any one of plural protocols. SOLUTION: A client requests the object stored in a server (190). The request of the object is received by a network (192). The request of the object is routed to one cache node by a network dispatcher (194). It is determined whether the cache node to receive the request of the object from the network dispatcher is the first owner of the object or not (196). When it is the first owner, the cache node serves the request of the client (197). Then, the first owner retrieves the requested object by communicating with the server (198).

    Abstract: Coordinated, hierarchical caching of objects in a client/server system. In the described embodiment, an encapsulated cluster 70 comprises one or more level 1 nodes 20, e.g. Web server accelerators or routers, each including at least one level 1 cache 30, and one or more level 2 nodes 40, e.g. Web servers, within which the objects are permanently stored or generated on request. Each level 2 node is coupled to at least one level 1 node and includes one or more level 2 caches 50. More levels can be included. Object caching is based on various described criteria: for instance, the level 2 cache(s) can be used to cache dynamic pages which are expensive to create, while the level 1 cache(s) can be used to cache static pages, and hot dynamic pages. Different cache replacement policies for the level 1 cache(s) are also described (Fig. 4), in order to optimize performance whether the performance bottleneck is router processing power, server processing power, or the network between the server(s) and the router.
