What are the various types of caching Caching is a technique widely used in computing to increase performance by keeping frequently accessed or expensive data in memory. In the context of a web application, caching retains the pages or data across HTTP requests and reuses them without the expense of recreating them. ASP. NET has 3 kinds of caching, strategies. Output, Caching. Fragment and Caching. Data. Caching. Output 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 entire page the page should have Output. Cache directive. lt Output. Cache Duration6. Vary. By. Paramstate 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 pagelt Output. Cache Duration1. Vary. By. ParamCategory. ID Selected. ID Data Caching Caches the objects programmatically. For data caching ASP. Net provides a cache object for eg cacheStates ds.
