Performance problem with localhost instead of 127.0.0.1

[wima75]

Could you make this configurable?

aspnetcore/src/Middleware/SpaServices.Extensions/src/AngularCli/AngularCliMiddleware.cs

Line 57 in c16eddc

task => new UriBuilder("http", "localhost", task.Result.Port).Uri);

On my system every call to the Angular Live Development Server with localhost will take about 4 seconds. If the call would be 127.0.0.1 instead of localhost it will take some milliseconds.

Localhost resolves to both ::1 and 127.0.0.1. IPv6 is tried first, times out after 5s, and falls back to IPv4.

Why is the development server listening only on IPv4?.

@Tratcher this is a dupe of another issue. The problem apparently is that node only listens on IPv4
