Based on the code provided in your previous (and open) question I presume you would need to set the Credentials property on the HttpWebRequest. Without knowing the specifics of your credential situation, I cannot say whether the DefaultCredentials will work or whether you will need to provide a user & password.
wr.Credentials = System.Net.CredentialCache.DefaultCredentials;
