    • Methods, systems, and computer program products are provided for prefetching and caching portal information in a client application in a logically separated client/server computing environment. Before a user requests a specific portlet view to be displayed at the user's web browser, portlet information from a server is prefetched. The portlet information may include content data to be displayed in a portlet view, meta data describing how the content data will be displayed, and combinations of both content data and meta data. The prefetching step is performed on the client of the logically separated client/server computing environment. The client stores the prefetched portlet. Once the prefetched portlet information has been stored, upon a user request such as clicking on a link in a portlet view, the method retrieves the stored portlet information and displays the portlet information in a corresponding portlet view. From the user's perspective, the portlet view may display new content information, previously viewed content information in a different format, or a combination of new content information and old content information presented in a different format.
    • 提供方法,系统和计算机程序产品,用于在逻辑分离的客户端/服务器计算环境中的客户端应用程序中预取和缓存门户信息。 在用户请求特定的Portlet视图显示在用户的Web浏览器之前,来自服务器的Portlet信息将被预取。 Portlet信息可以包括要在portlet视图中显示的内容数据,描述内容数据将如何被显示的元数据,以及内容数据和元数据两者的组合。 预取步骤在逻辑分隔的客户机/服务器计算环境的客户端上执行。 客户端存储预取的portlet。 一旦预取的Portlet信息已被存储,在用户请求(例如在portlet视图中单击链接)时,该方法检索存储的portlet信息并在相应的Portlet视图中显示Portlet信息。 从用户的角度来看,portlet视图可以以不同的格式显示新的内容信息,先前观看的内容信息,或以不同格式呈现的新内容信息和旧内容信息的组合。
