What is Caching in Asp Dot Net

Caching in Asp.Net

This is very important and interesting concept by Asp.Net. As we all are dealing with dynamic websites where interaction of user is available. There is images on pages, menus are on pages, some media files, advertisements are going on.
Caching is basically send the data to users as per their requirements so we can improve the performance of our application.

Cache is basically stored the generated output by page in a temporary memory.

Types of Cache in Asp.Net as below
1.Page Caching
2.Fragments caching
3.Data Caching

* Page Caching

To cache an entire page's output we need to specify a directive at the top of our page, this directive is the @ OutputCache.
<%@OutputCache Duration= 50 VaryByParam= none %>

* Fragment caching
In some scenarios we only need to cache only a segment of a page.
Like master page and webuser controls

* Data Caching
We can store objects in memory very easily and use them depending on our requirements anywhere on the page.
1.Cache["Website"]= Visual Coder ;
2.Cache.Insert("Website",strName,new CacheDependency(Sever.MapPath("Test.txt"));
