Difference is who (IIS/ASP.NET) returns 404 error.

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 how to show throw 404Error(); } asp.net http exception share|improve this question asked Feb 11 '11 at 22:05 Earlz 25.8k56207401 add a comment| 2 Answers 2 active oldest votes up vote 24 down vote accepted 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. share|improve this answer answered Feb 11 '11 at 22:07 Darin Dimitrov 691k16225062379 Hmm. If this exception was thrown when CustomErrors is off, will it show the standard ASP.Net exception page with a stacktrace? –Earlz Feb 11 '11 at 22:08 2 @Earlz, if customErrors="Off" you will probably get an YSOD. –Darin Dimitrov Feb 11 '11 at 22:09 I was just curious for when in a development environment. That seems to work though! –Earlz Feb 11 '11 at 22:11 add a comment| up vote 12 down vote A much better way is: 'Throws a 404 Not found: Response.Clear() Response.StatusCode = 404 Response.End() There is no need to throw an exception and the above works much better when using cu
