Hi Vineet, Normal 0 Caching is a technique widely used in computing to increase performance by keeping frequently accessed or expensive data in memory. In context of web application, caching is used to retain the pages or data across HTTP requests and reuse them without the expense of recreating them.ASP.NET has 3 kinds of caching strategiesOutput CachingFragment CachingData CachingOutput Caching: Caches the dynamic output generated by a request. Some times it is useful to cache the output of a website even for a minute, which will result in a better performance. For caching the whole page the page should have OutputCache directive. Fragment Caching: Caches the portion of the page generated by the request. Some times it is not practical to cache the entire page, in such cases we can cache a portion of page Data Caching: Caches the objects programmatically. For data caching asp.net provides a cache object for eg: cache["States"] = dsStates; Please refer the below links http://www.dotnetfunda.com/articles/article1484-how-to-implement-fragment-caching-in-aspnet.aspx http://www.aspnettutorials.com/tutorials/performance/caching-varyby-cs.aspx http://www.4guysfromrolla.com/articles/022802-1.aspx Thanks
