Possible to throw a 404 error within an ASP.Net page?

Question

I was wondering if it's possible to throw a 404 error from within a page(code behind)? Or possibly even throw any other type of error page such as 408(timeout) or 401(authentication required)?

Note: I don't just want to have the page return a status code of 404, I want it to use the ASP.Net(or my CustomErrors) 404 error page.

Something like this in the code behind:

if(id>10){ //if id is greater than 10, then it doesn't exist here   throw 404Error(); }

You could throw an HttpException and set the corresponding status code:

throw new HttpException(404, "Not found"); 

It will also work with other status codes. Just a remark about the 401: as you probably know when ASP.NET MVC detects this code it automatically redirects you to the login page and getting a custom error page for the 401 status code could be a real PITA to implement.
