title: Web request (GET) with Basic Auth and SSL failing
body: <p>I have browsed through all questions in stackoverflow but I still cannot make my request working. The server (I have no access to it, so I do not know what is going on over there) is always responding with 403.</p>
  
  <p>I was told that I have to use Basic Auth with HTTPS. At first I tried it with PostMan (Chrome add-on) and it worked perfectly. Fiddler says that PostMan has sent this request:</p>
  
  <pre><code>GET https://mypage.com/api/topic HTTP/1.1
  Host: mypage.com
  Connection: keep-alive
  Authorization: Basic asdfasdfasdfasdfasdfasdf
  Cache-Control: no-cache
  User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.99 Safari/537.36
  Postman-Token: 7363b868-cc6e-1dff-d5d0-c7a0c1924fa7
  Accept: */*
  Accept-Encoding: gzip, deflate, sdch
  Accept-Language: en-US,en;q=0.8
  Cookie: JSESSIONID=imxY132456123Scai90Nrsv
  </code></pre>
  
  <p>I wanted to reproduce this in our C# application, but whatever I try I get a 403 answer from the server. This is (one) of the versions in C# I have tried:</p>
  
  <pre><code>NetworkCredential nc = new NetworkCredential(Login, Password);
  CredentialCache cc = new CredentialCache();
  cc.Add("mypage.com", 443, "Basic", nc);
  
  WebRequest request = WebRequest.Create("https://mypage.com/api/topic");
  request.Credentials = cc;
  request.PreAuthenticate = true;
  request.Method = "GET";
  WebResponse response = request.GetResponse();
  </code></pre>
  
  <p>That is what is sent according to Fiddler:</p>
  
  <pre><code>GET https://mypage.com/api/topic HTTP/1.1
  Host: mypage.com
  Connection: Keep-Alive
  </code></pre>
  
  <p>Obviously there are some things missing. I am wondering which ones (like user-agent?) are really essential and I hope you can help me fix the problem.</p>
