Equivalent to LocalRedirect in Blazor

[danroth27]

In MVC & Razor Pages you can all LocalRedirect() to trigger a redirect to page in the app. This is typically used with return URLs specified in the request, so that a malicious request can't send you off to some other site.

In Blazor we have NavigationManager.NavigateTo(). Do we need a NavigateToLocal()?

@danroth27 thanks for contacting us.

It's not that relevant, since the main use case is redirects in auth. In other scenarios you can implement this with a few lines of code:

var relative = navigationManager.ToBaseRelativeUri(uri);
if(relative == uri){
   throw new invalidoperationexception
}
navigationManager.NavigateTo(relative);

It seems incorrect to me to throw in this case. This is a problem with the request, not a necessarily a server error. However, it does appear that LocalRedirect throws and ToBaseRelativePath will throw if the passed in URI is not relative to the base URI. So the behavior is consistent.
