Same as UrlMapping model, create a class that should be generated by IHttpModule, then add its referance to Web.config

public class MasterPageModule: IHttpModule
{    
public void Init(HttpApplication context)
{
context.BeginRequest += new EventHandler(context_BeginRequest);
}

void context_BeginRequest(object sender, EventArgs e)
{
 //your code
}
}
