　　 外文原文 ASP.NET Caching Function with the Creation of High Performance Web Jonothon Ortiz, 《ASP.NET Web Developers Guide (VBL)》 Introduction Since the birth of the Internet, IT and development staff has been facing such problems, that is, how to create rapid response to user requests for Web applications, especially if the server is processing a large number of requests can respond quickly to user requests for Web applications. ASP.NET model provides many buiblt-in functions to enhance performance, caching is one of the important functions. Brief In practice, the generation of high performance, Scalable Web applications most important factor is one of the first to request these items will be stored in the Web services Treasury or request for a stream of other software, such as proxy servers or browsers, to avoid re-establish previous request to meet the information, particularly those requiring a large number of processor time or resources. This is commonly referred to the cache, It allows the use of a variety of technologies across HTTP request page output or storage application data and its reuse, Servers do not need to re-create information, thereby saving time and resources. ASP.NET provides two can be used to build high-performance Web caching application types. The first one is called the output cache, It allows dynamic page or user control response stored in the output stream (launched from the server to request the browser) with any H TTP1.1 cache function of equipment. When behind at the time of the request,the non-implementation of a page or user control code for the output buffer to meet the request. The output buffer cache may be targeted at the entire page, and can also be part of page. The second type of cache is a traditional application data cache, It can be used to programmatically arbitrary object (eg, data sets) storage memory to the server, so that Application procedures can save these objects re-establish the necessary time and resources.
