content and a result code. The result code is not shown to the user but processed by the program accessing the server ("client"). The result code is a code for the client telling it the status of the content that it just sent There are several result response.statuscode = 404 codes, but the ones we'll look at now are "404" and "200". The result code 200 means that

The result code 404 means that the page the client wanted is not available, but c# set response status code it can also return content (eg. a page saying "sorry, couldn't find your page"). Usually a normal web page returns 200, saying all is ok. Background - custom error pages Anyone who has ever looked for something special on the web will be able to
Asp.net Mvc Custom Error Page
tell stories of the "URL that got away" -- the link to the page with exactly the content you were looking for, that just doesn't work anymore. More and more, as people update their sites, URLs aren't valid for that long of a time - people moving from "Frontpage" to a content-management-system (CMS), or from one CMS to another. When they move, the old links usually become invalid, inside of the new site it shows the correct links, but coming from the outside it'll more than likely have old, obsolete tryskipiiscustomerrors not working links. So you find the page you were looking for -- and then just get a boring "404 - not found.". The people making these sites know that this is always going to happen sooner or later. So what can you do? Many sites now have custom error pages, so instead of landing on a plain "nothing found" page, you'll land on a page with lots of information about the sites, other links that might be interesting or similar to the link you were looking for. These custom error pages are a good thing - they help get people back on track, possibly helping them find the page they were originally looking for (or at least something similar). Sometimes, instead of an error page it will just redirect you to the starting page of the site, letting you go from there. However, these custom error pages need to be set up correctly in order to work according to the web standards. A lot of sites just redirect errors to the error page, and the error page then returns ... result code "200" - meaning "I found what you were looking for". This is not the way it should be - an error page should always return 404 (at least for bad URLs, other errors have other codes). An error page with the result code 404 can still show exactly the same content as an error page with the result code 200. The user will not be able to tell the difference - but the software will. Check to see if your server returns 404 or 200 To

Extending Umbraco Is it possible to get Umbraco to return a "proper" 404 status code instead of 200 OKfor the custom page not found page? I know the standard .Net error handling does the same thing, but I can get round that by adding: Response.StatusCode = 404; to the page. If I try and do the same in Umbraco, it just fires off the 404 handler again, effectively resulting in an infinite loop as the custom error custom 404 page throws a 404 status, and then gets redirected back to itself and so on. I've not really found much on this from looking so far, I'm sure someone must have found a way round this! Any help or pointers greatly appreciated. :) Copy Link Tim 1172 posts 2568 karma points Oct 04, 2010 @ 16:00 2 Sorted, I needed to tell it to ignore IIS errors as well. Adding the following code to the template custom error page for the 404 page sorts it (you could add similar code in an XSLT extension I guess too): protected override void Render(HtmlTextWriter writer) { base.Render(writer); Response.TrySkipIisCustomErrors = true; Response.StatusCode = 404; Response.StatusDescription = "404 Page Not Found";} This is the important bit: Response.TrySkipIisCustomErrors = true; if you don't have that line in and you're running IIS7 or above, you'll run into the infinite looping that I described earlier! Hope that helps anyone else who has this problem! Copy Link David Conlisk 427 posts 972 karma points Apr 23, 2012 @ 12:55 0 Excellent Tim - thanks! Copy Link John Perryn 68 posts 178 karma points Dec 23, 2013 @ 15:30 0 Hi Tim I'm having exactly this problem - all url errors are routed to my 404 page which works OK but the page returns "200 OK" to the caller. I do not understand how to "add the code to the 404 template". I'm running umbraco v 4.11.8 Regards John Perryn Copy Link Tim 1172 posts 2568 karma points Dec 23, 2013 @ 15:43 0 Hi John, Umbraco 4.11.8 should return actual 404 statuses for not found content (this was a bug on much older versions of Umbraco). How have you wired in the 404 page? Are you using the customerrors section in the web.config file, or the Umbraco 404 page configuration in umbracoSettings.config? Copy Link John Perryn 68
