HTTP 404 : Resource Not found - Custom error

Question

Hello, I'm newbie to MVC, trying to create a custom error page and show when user is looking for resource which isn't available. Followed few articles and able to show an custom error page. https://stackoverflow.com/questions/717628/asp-net-mvc-404-error-handling?answertab=votes#tab-top I have created an Error Controller with 'NotFound404()' action method and view is created with the same name 'NotFound404.cshtml'. public class ErrorController : Controller { // GET: Error public ActionResult NotFound404() { return View(); } } Web.config system.web > customErrors mode = "On" > error statusCode = "404" redirect = "~/Error/NotFound404" /> customErrors > system.web > When i try to access any unknown resource, i can see the notfound404.cshtml. But when i inspect url it shows as 'http://localhost:xyzw/Error/NotFound404?aspxerrorpath=/New'. Why do i get such wierd url? and i'm not using any aspx pages but it shows aspx in url. HTTP status under F12-Developer tools- Network - shows 200 OK. which isn't correct. How to rectify this. And when i tried to access any static html page instead of a new controller/ action-view system.web > customErrors mode = "On" > error statusCode = "404" redirect = "~/Shared/NotFound.html " /> customErrors > system.web > 404 Error occurs is this error because of looking up for wrong path.? My application folder structure How to fix these errors and please show a right way to configure these error handling strategies. Thanks in advance.

Hello I observed your code , and you might left to use defaultRedirect property , just you need below snippet : "On" defaultRedirect= "NotFound.html" > "404" redirect= "404NotFound.html" /> "500" redirect= "500NotFound.html" /> Still you can see .aspx in url [which actually new for me] For more reference you can follow in-depth article : - By Microsoft : https://docs.microsoft.com/en-us/aspnet/web-forms/overview/older-versions-getting-started/deploying-web-site-projects/displaying-a-custom-error-page-cs https://msdn.microsoft.com/en-us/library/h0hfz6fc(v=vs.85).aspx - Other Aricles : https://www.c-sharpcorner.com/UploadFile/618722/custom-error-page-in-Asp-Net-mvc/ https://www.c-sharpcorner.com/UploadFile/092589/custom-error-page-in-Asp-Net/ https://love2dev.com/blog/properly-using-custom-error-pages-in-aspnet/ I hope you will find it useful Thanks

Hello Have you tried by setting proper file path like below : defaultRedirect="~/shared/notfound.html' I think problem with path only , you should provide its relative path , just try to change path and do R & D on it Thanks

Thanks Manav Pandya, Hiten Pandya for your response. I tried defaultRedirect= "NotFound.html" But the same HTTP 404 Error screen is shown. And Manav, i have gone thru the aricles given but couldn't figure out my mistake what's going wrong with my application. When i use `Controller/Actionmethod` in redirect="Error/NotFound404" in web.config it shows custom error page when i navigate to 'http://localhost:xyzw/New' but when i try navigating to 'http://localhost:xyzw/shared/notfound.html' this again shown HTTP 404 Error screen. Can't figure out what's going wrong.
