title: Passing current windows authentication credentials when redirect user to different page
body: <p>I currently have 2 ASP .NET sites running on the same IIS server, both sites are using windows authentication. When I redirect users from one site to another, the users are asked to re-enter their username and password, even though they are using the same user/pass to login into both site.</p>
  
  <p>Is it possible to pass the credentials when doing the redirection so that user only have to login once?</p>
  
  <p>I have found a somewhat related question here:</p>
  
  <p><a href="https://stackoverflow.com/questions/4918682/building-a-credentialcache-for-httpwebrequest-credentials-when-redirects-are-ukn">Building a CredentialCache for HttpWebRequest.Credentials when redirects are uknown</a></p>
  
  <p>But that method only allow me to send request from one side to another instead of a full redirect.</p>
