ASP.NET Interview question :- How do we write a HttpHandler ?

This is a simple a .NET Interview question .Its a two step process.

First create a class which implements Ihttphandler

public class clsHttpHandler : IHttpHandler
{

    public bool IsReusable
    

{
        get { return true; 

}
    }

    public void ProcessRequest(HttpContext 

context)
    {
       // Put 

implementation here.
    }
}

Step 2 make a entry in the web.config file.

<httpHandlers>
<add verb="*" path="*.gif" 

type="clsHttpHandler"/>
</httpHandlers>
