ASP.NET interview question :- How do we write a HttpModule ?

Answer:
 

Again a simple .NET Interview question Writing a HttpModule is a two step process.

Create a class which implements IhttpModule. 

    public class clsHttpModule : IHttpModule
    {

    public void Init(HttpApplication context)
    {
       this.httpApp = context;
       httpApp.Context.Response.Clear();
       httpApp.AuthenticateRequest += new EventHandler(OnAuthentication);
       httpApp.AuthorizeRequest += new EventHandler(OnAuthorization);
    ....
    ....
    ....
   
    }
    void OnAuthorization(object sender, EventArgs a)
    {
        //Implementation
    }
    void OnAuthentication(object sender, EventArgs a)
    {       
        //Implementation
    }    
    }

 Make a entry in the web.config file.

   <httpModules>
   <add name="clsHttpModule" type="clsHttpModule"/>
   </httpModules>
