404 Html Template
In Symfony applications, all errors are treated as exceptions, no matter if they are just a 404 Not Found error or a fatal error triggered by throwing some exception in your code. In the development environment, Symfony catches all the exceptions and displays a special exception page with lots of debug information to help you quickly discover the root problem: Since these pages contain a lot of sensitive internal information, Symfony won't display them in the production environment. Instead, it'll show a simple and generic error page: Error pages for the production environment can be customized in different ways depending on your needs: If you just want to change the contents and styles of the error pages to match the rest of your application, override the default error templates; If you also want to tweak the logic used by Symfony to generate error pages, override the default exception controller; If you need total control of exception handling to ex

I've searched around this site and various others and have seen a few implementations of this. EDIT: I forgot to mention I am using RC2 Using URL Routing: routes.MapRoute( "Error", "{*url}", new { controller = "Errors", action = "NotFound" } // 404s ); The above seems to take care of requests like this (assuming default http://stackoverflow.com/questions/619895/how-can-i-properly-handle-404-in-asp-net-mvc route tables setup by initial MVC project): "/blah/blah/blah/blah" Overriding HandleUnknownAction() in the controller itself: // 404s - handle here (bad action requested protected override void HandleUnknownAction(string actionName) { ViewData["actionName"] = actionName; View("NotFound").ExecuteResult(this.ControllerContext); } However the previous strategies do not handle a request to a Bad/Unknown controller. For example, I do not have a "/IDoNotExist", if I request this I get the generic 404 page from the web server and not my 404 if I use routing + override. So finally, my question is: Is there any way to catch this type of request using a route or something else in the MVC framework itself? OR should I just default to using Web.Config customErrors as my 404 handler and forget all this? I assume if I go with customErrors I'll have to store the generic 404 page outside of /Views due to the Web.Config restrictions on direct access. Anyway any best practices or guidance is appreciated. asp.net-mvc http-status-code-404 share|improve this question edited Jun 20 '11 at 21:05 zvolkov 12.5k84970 asked Mar 6 '09 at 18:21 Brian 1,8643107 3 it's 404 error, i would just not bother about it. let it display 404. as definitely user mistyped something. or if it is something thats moved then your application shou
you click a link and encounter a "404 File Not Found" error? Do you: Click on the BACK button of your browser and go somewhere else? Try to http://www.thesitewizard.com/archive/custom404.shtml back up one directory in the URL (ie, web address) and try again? Write to the webmaster of the site and the referring site to inform them of the situation? If you are like most people, you'll simply click on the BACK button and try another place. The majority of people don't even know that there are any other alternatives. You thus need to do something so that you do not lose this 404 error group of people who come to your site by following an old link or by typing your URL incorrectly. Requirements for Customizing the 404 File Not Found Page It is not possible to customize your 404 error page if your web host has not enabled this facility for your website. For example, at the time of this writing, if you host at free web hosts like Geocities or Tripod, you will not be 404 error page able to customize your 404 Error Page. Commercial web hosts, on the other hand, usually provide this facility. If your web host supports a way to customise your 404 file, you will usually find mention of it somewhere in their documentation (or advertisements). In fact, if they mention somewhere that you can customize a file named ".htaccess", it probably means that you can also customize your 404 File Not Found error page. The .htaccess file is what Apache web servers use to allow you to fine-tune your web server configurations at a directory level. Other types of web servers handle the customization of 404 error pages differently. (A web server, in this context, is the software that runs on your web host's computer. It is the program that "serves" your web pages to your visitors.) Step One: Creating/Modifying the .htaccess File This step may not be necessary in all situations. Some web hosts already configure their web server so that it will look for a specific file in your web directory when a certain document cannot be found. If so, simply skip this step. If your web server is not an Apache web server, you will have to find out from your web host what you need to do to enable the server to serve your c
