ASP Caching

Caching

 Duration --> TIme taken between 2 cache

VarByParam --> give controls id to filter cache

Location --> set where cache file store (server,client,proxy)  

important

1. VarByParam can be only one contrall.

<%@ OutputCache Duration ="30" VaryByParam="None" %>

Duration --> cach duration in second

<%@ OutputCache Duration ="30" VaryByParam="ddProducts" %>
cache for every single entity in list box
<Asp:DropDownList id ="ddProducts">
<Item> One </Item>
<Item> Two</Item>
<Item> Three</Item>
<Item> Four</Item>
</Asp:DropDownList>


Fragment Caching
Fragments are User contralls
set each and every user contral to cache derective
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="WebUserControl1.ascx.cs" Inherits="SEcond.Cache.WebUserControl1" %>
<%@ OutputCache Duration="30" Shared="true"  VaryByParam="None"%>
