How to add Header and Footer on every page by using HttpModule in asp.net

In this post,I will show you a very simple way to add header and footer on every page using HttpModule.

  • Open visual studio and create a new website.
  • Right click on website and add a new class named HeaderAndFooter,and inherit this class with IHttpModule inteface.
using System;
using System.Web;
using System.IO;

public class HeaderAndFooter : IHttpModule
{
    const string PageHeaderText = "<h1>Header Added by Module<h1>";
    const string PageFooterText = "<h1>Footer added by Module</h1>";

    public void Init(HttpApplication app)
    {
        // Register for pipeline events
        app.BeginRequest += new EventHandler(OnBeginRequest);
        app.EndRequest += new EventHandler(OnEndRequest);
    }

    public void Dispose()
    {
        // Nothing to do here
    }

    public void OnBeginRequest(object sender, EventArgs e)
    {
        HttpApplication app = (HttpApplication)sender;
        HttpContext ctx = app.Context;

        // Add custom header to the HTTP response
        ctx.Response.AppendHeader("Author", "DinoE");
        ctx.Response.Write(PageHeaderText);
    }

    public void OnEndRequest(object sender, EventArgs e)
    {
        // Get access to the HTTP context 
        HttpApplication app = (HttpApplication)sender;
        HttpContext ctx = app.Context;

        // Append some custom text
        ctx.Response.Write(PageFooterText);
    }
}
  • Open the web.config and register the module as below
<?xml version="1.0"?>
