hi One of the most important factors in building high-performance scalable Web applications is the ability to store items whether data objects pages or parts of a page in memory the initial time they are requested. You can store these items on the Web server or other software in the request stream such as the proxy server or browser. This allows you to avoid recreating information that satisfied a previous request particularly information that demands significant processor time or other resources. Known as caching it allows you to use a number of techniques to store page output or application data across HTTP requests and reuse it. Thus the server does not have to recreate information saving time and resources. ASP.NET provides two types of caching that you can use to create high-performance Web applications. The first is called output caching which allows you to store dynamic page and user control responses on any HTTP 1.1 cache-capable device in the output stream from the originating server to the requesting browser. On subsequent requests the page or user control code is not executed; the cached output is used to satisfy the request. The second type of caching is traditional application data caching which you can use to programmatically store arbitrary objects such as data sets to server memory so that your application can save the time and resources it takes to recreate them. please refer http://msdn.microsoft.com/en-us/library/06bh14hk%28v=vs.71%29.aspx http://www.c-sharpcorner.com/UploadFile/vishnuprasad2005/ImplementingCachinginASP.NET11302005072210AM/ImplementingCachinginASP.NET.aspx hope this help.

Hi Akshay Normal 0 Catching:- It is a performance improvement technique. 1.It handles storage of frequently accessed data in the memory of the system so that user can access data very quickly. 2.It is used to store recently visited webpage.suppose we are surfing the site and watching various pages. At the time we want to go back to the previous page it loads the page from the memory instead of the server. 3.It has a disadvantage too. Supose the website is continuously updated the user is not able to watch the changes. Refer http://www.codeproject.com/KB/web-cache/cachingaspnet.aspx Thanks
