An overload of `UseStatusCodePages` takes a content type and format string:

### Redirect re-execute extension methods
There are also redirect and re-execute extension methods. The redirect method sends a *302 Found* status code to the client and redirects the client to the provided location URL template. The template may include a `{0}` placeholder for the status code. URLs starting with `~` have the base path prepended. A URL that doesn't start with `~` is used as is.

* Sends a *302 - Found* status code to the client.
* Redirects the client to the location provided in the URL template.
The template may include a `{0}` placeholder for the status code. The template must start with a forward slash (`/`).

The re-execute method returns the original status code to the client and specifies that the response body should be generated by re-executing the request pipeline using an alternate path. This path may contain a `{0}` placeholder for the status code:

If using a `UseStatusCodePages*` overload that points to an endpoint within the app, create an MVC view or Razor Page for the endpoint. For example, the [dotnet new](/dotnet/core/tools/dotnet-new) template for a Razor Pages app produces the following page and page model class:
