URL Reservations

When you host a website within IIS, reserving a URL so that traffic is directed to your IIS website and not a different website on the machine is done for you. It's something you don't event think about. This is called a URL Reservation, and a new URL Reservation is added via the command netsh http add url=url user=user

The Nancy Self Host does this for you too, however netsh needs Administrator privileges. Normally Windows services run in a less permissive context (as Network Service or Local Service) so the only time to add a URL Reservation is during install as installing a service requires Administrator privileges.

If your service is running with restrictive permissions then you can specify that URL Reservations be created at install time like so.

s.WithNancyEndpoint(x, c =>
{
    c.AddHost(port: 8080);
	c.CreateUrlReservationsOnInstall();
});
	

By default any URL Reservations added will also be deleted when the service is uninstalled.
