How can a Blazor server side app redirect from http://hostname to http://hostname/route1 on load?

Question

For several of the sites I have built using MVC/TypeScript or MVC/Angular I have needed to redirect the user immediately from http://hostname to http://hostname/route1. I am trying to figure out how to implement the same functionality with Blazor Server Side.

I am aware that this can be done using the IIS URL Rewrite engine, however, it has not been determined if the application will be hosted under IIS, self-hosted on Windows, or hosted on Linux.

Is this possible? If so, what is the best practice approach for this implementation?

Thanks

You could redirect on the index components OnInitialized() method by calling an injected NavigationManager to redirect to your desired location. — olabacker, Jan 27 '21 at 20:44
Thus you're making the Index component useless as whenever the user tries to reach the Index page, he's automatically redirected to the desired location. This solution is rather impractical, no ? — enet, Jan 27 '21 at 23:45

You can do a redirect on OnInitialize on your root page (maybe index.razor )

@page "/"
@inject NavigationManager MyNavigationManager
@code
{
    protected override void OnInitialized()
    {
        MyNavigationManager.NavigateTo("route1");
    }
}

Thank you everyone. You provided a starting point.

I changed MainLayout.razor to override the OnInitialized method.

@inject NavigationManager MyNavigationManager
@code
{
    protected override void OnInitialized()
    {
        var currentUri = new Uri(MyNavigationManager.Uri);
        if (currentUri.AbsolutePath == "/")
                MyNavigationManager.NavigateTo("route1");
    }
}
