Basic URL rewriting without file extension

How you can rewrite the url which can work without entering file extension.

You have to add this code in Global.asax file:

void Application_BeginRequest(object sender, EventArgs e)
{
string curruntpath = Request.Path.ToLower().Trim(); ;

bool endsswith = curruntpath.EndsWith(".aspx");
HttpContext obj = HttpContext.Current;
if (!endsswith)
{
curruntpath = curruntpath + ".aspx";
}
if (System.IO.File.Exists(Server.MapPath(curruntpath)))
{
obj.RewritePath(curruntpath);
}
else
{
obj.RewritePath("Error.aspx");
}


}
