You are creating an ASP.NET Web site. You create a HTTP module named CustomModule, and you
register the module in the web.config file. The CustomModule class contains the following code.
public class CustomModule : IHttpModule
{
string footerContent = “<div>Footer Content</div>”;
public void Dispose( ) {}
}
You need to add code to CustomModule to append the footer content to each processed ASP.NET
page.
Which code segment should you use?

A.
public CustomModule(HttpApplication app)
{
app.EndRequest += new EventHandler(app_EndRequest);
}
void app_EndRequest(object sender, EventArgs e)
{
HttpApplication app = sender as HttpApplication;
app.Response.Write(footerContent);
}

B.
public void Init(HttpApplication app) {
app.EndRequest += new EventHandler(app_EndRequest);
}
void app_EndRequest(object sender, EventArgs e)
{
HttpApplication app = new HttpApplication();
app.Response.Write(footerContent);
}

C.
public CustomModule()
{
HttpApplication app = new HttpApplication();
app.EndRequest += new EventHandler(app_EndRequest); }
void app_EndRequest(object sender, EventArgs e)
{
HttpApplication app = sender as HttpApplication;
app.Response.Write(footerContent);
}

D.
public void Init(HttpApplication app)
{
app.EndRequest += new EventHandler(app_EndRequest); }
void app_EndRequest(object sender, EventArgs e)
{
HttpApplication app = sender as HttpApplication;
app.Response.Write(footerContent); }
