What is caching and types of caching
This is technique use to increase performance by keeping access data in fast way.The request for a
cached file or data from the actual location
There are three kind of caching
1.Output Caching
Response.Cache.SetExpires(DateTime.Now.AddMonths(1));
Response.Cache.SetCacheability(
HttpCacheability.ServerAndPrivate);
Response.Cache.SetValidUntilExpires(true);
2.Fragment Caching
Create a user control
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="amrit.ascx.cs" Inherits="WebUserControl" %>
<%@ OutputCache Duration="5" VaryByParam="None" %>
<asp:Label ID="lblTime" runat="server" Font-Bold="true" ForeColor="Blue" />
create a page and define datetime on load event
protected void Page_Load(object sender, EventArgs e)
{
lblTime.Text = DateTime.Now.ToString();
}
<%@ Register src="amrit.ascx" tagname="WebUserControl" tagprefix="uc1" %>

<p>Refresh the Page Time Will Update Only After Every 5 Seconds</p>
<uc1:WebUserControl ID="WebUserControl1" runat="server" />
</div>
