摘要： The invention provides a method and system for sending relatively identical web pages, when requested by subsequent users, with substantial reduction of bandwidth. The server determines a “template web page” corresponding to the actual information on the web page, and having a set of insertion points, at which changed data can be inserted by the client. The server sends a JavaScript program corresponding to the template web page, which makes reference to the template web page and the changed data, along with sending the actual changed data itself. A first user requesting the web page receives the entire web page, while a second user requesting the web page (or the first user re-requesting the web page at a later time) receives the template information plus only the changed data. The server re-determines the template web page from time to time, such as when a ratio of changed data to template web page data exceeds a selected threshold. The server identifies the particular template web page to the client using a unique identifier (an “E-tag”) for the particular data sent in response to the request. Since the E-tag refers to the template, not the underlying web page, when the standard client makes its conditional request for the web page “if not changed”, the server responds that the web page is “not changed” even if it really is, but embeds the changed data in a cookie it sends to the client with the server response to the client request.

摘要： The invention provides a method and system for fetching network objects from a server, such as used in conjunction with an internetworking environment. A web server maintains information regarding which web pages are most likely to be requested by users, and pre-downloads those web pages to associated web clients in advance of actual requests being made by the user. This allows the user to receive the web page prior to actual request, and thus reduces time the user waits for delivery of the web page. The web server maintains statistical information responsive to requests for information made by users, to estimate which links between web pages are most likely to be followed. The web server provides this information to web clients as hints for pages for web clients to pre-download. The web server also maintains rules regarding web pages most desirable to present to users, to provide the greatest value for the web site. These rules can be responsive to statistical measures, to information about categories of users, to demographic information, to past behavior of specific users at the web site, or to other relevant factors. Examples described herein relate to web pages, but the invention is broadly applicable to many different types of requests for information (such as for example database queries and other libraries of information).
