Prevent the browser from caching the ASPX page

​use this code to prevent the browser from caching the ASPX page.

By default browser cache the page. sometimes we don't require the page to be cached.

It will work for IE, Mozilla, and Chrome. I didn't checked the below code for other browsers.

<%@ Page language="c#" AutoEventWireup="true" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
<html xmlns="" >
    <title>HttpCachePolicy - SetNoStore - C# Example</title>
    <script runat="server">
      void Page_Load(Object sender, EventArgs e) 
        // Prevent the browser from caching the ASPX page

        // Display the DateTime value.
        Label1.Text = DateTime.Now.ToLongTimeString();
    <form id="Form1" method="post" runat="server">
      <h3>HttpCachePolicy - SetNoStore - C# Example</h3>

      <p>Click the Submit button a few times, and then click the Browser's Back button.<br />
      You should get a "Warning: Page has Expired" error message.</p>

      <p>Time:  <asp:Label id="Label1" runat="server" Font-Bold="True" ForeColor="Red" /></p>

      <asp:Button id="Button1" runat="server" Text="Submit" />

Happy Coding !!
