Question

I have 4 servers participating in load balancing environment. The same ASP.NET application is being hosted in each server.
I would like to get the DNS Name regardless of the underlying server.
Which one of the followings will give the correct answer?

Request.Url.Host
Environment.MachineName
System.Net.Dns.GetHostName() 

Thanks for your suggestion!

Answer 1

You could try Request.Url.GetLeftPart(UriPartial.Authority). So for example if the request url is http://www.contoso.com/index.htm?date=today this will return http://www.contoso.com.
