Question

How to handle invalid URLs in MVC?

For ex.: When the user enters http://localhost/User/MyProfile instead of http://localhost/User/Profile, it will throw an exception.

How to handle this request?

Answer 1

You need first to add a custom Error page url in the web.config:

<customErrors mode="On" defaultRedirect="~/Error/404" />  

And add a controller to handle the invalid urls:

public class ErrorController:Controller
    {
        [ActionName("404")]
        public ActionResult Error404()
        {
            return View("Error");
        }
    }

And if you want to redirect the user to the home page then you don't need the Error controller just modify the custom error tag:

<customErrors mode="On" defaultRedirect="~/Home/Index" />
