I am trying to secure an https post service through a username/password authentication (Basic authentication). But so far I am not able to figure out how I can secure my service on the server side and force the username/password combination for the clients. I get that using httpclienthandler/httpclient/networkcredentials you can access the server, but how to force it on the server side and send appropriate unauthorized access errors etc.
Any directions or links using C#?
