The question was how I can now intercept calls like

? There is no controller ! So – middleware to help!

For reading about middleware, please see https://docs.microsoft.com/en-us/aspnet/core/fundamentals/middleware/?view=aspnetcore-3.0

For rewriting, please see https://docs.microsoft.com/en-us/aspnet/core/fundamentals/url-rewriting?view=aspnetcore-3.0

Anyway, this is my code:

var service = app.ApplicationServices.GetService<LoadExchangeProviders>();
foreach (var item in service.Banks())
{
app.MapWhen(cnt =>
cnt.Request.Path.Value.StartsWith(“/” + item + “/”, StringComparison.InvariantCultureIgnoreCase)
||
cnt.Request.Path.Value.EndsWith(“.” + item, StringComparison.InvariantCultureIgnoreCase)
, HandleBank);
}

Figures also that previous answer was a string, not an object – changing return type to string
