Kestrel no longer ignores the hostname supplied to --server.urls

[halter73]

Take the following project.json snippet:

"commands": {
    "kestrel": "Microsoft.AspNet.Server.Kestrel --server.urls http://localhost:5000"
}

Prior to beta8, Kestrel would bind to IPAddress.Any even if localhost was specified via server.urls meaning that Kestrel would respond to remote requests. Starting in beta8, this bug has been fixed, so Kestrel will only respond to loopback requests if localhost is specified.

To continue responding to remote requests, specify "*" instead of "localhost" when you provide server.urls. Technically, any hostname that isn't "localhost" or a valid IPv4 or IPv6 address will cause Kestrel to bind to all network interfaces. Ex:

"commands": {
    "kestrel": "Microsoft.AspNet.Server.Kestrel --server.urls http://*:5000"
}
