Why is get_url adding an extra 'http://'? -- DB request fail

I used the Server Side Highscore code I found on the Wiki and added my own customized IEnumerator:

 public string userScoreURL = "http://xxxxx.com/displayUser.php?";
     IEnumerator GetUserScore(string username)
     {
         Debug.Log ("Loading scores");
         string get_url = userScoreURL + "user=" + WWW.EscapeURL(username);
         Debug.Log (get_url); // Used to see what URL it's trying to pass
         
         WWW hs_get = new WWW(get_url);
         yield return hs_get;
         
         if(hs_get.error != null)
         {
             print("There was an error getting your score: " + hs_get.error);
         }
         else
         {
             Debug.Log(username + " : " + hs_get.text);
         }
         
     }

This is the way I'm using it (bare with me, I'm not an expert): - I created a public method which contains a Subroutine calling the IEnumerator:

 public void GetUserScoreCoRoutine(string username)
     {
         StartCoroutine(GetUserScore(username));
     }

• From a different script I'm passing the username I'm trying the score for:

  public HSController HSScript;

     // Use this for initialization
       void Start () {
           HSScript = GetComponent<HSController>();
           HSScript.GetUserScoreCoRoutine("Tim"); //Tim needs to be replaced by playerPref later on
       }
  
  

So this fails and the I can see from my debug log that the URL passed looks like this: http://http://xxxxx.com/displayUser.php?user=Tim UnityEngine.Debug:Log(Object) c__Iterator2:MoveNext() (at Assets/Script/HSController.cs:89) UnityEngine.MonoBehaviour:StartCoroutine(IEnumerator) HSController:GetUserScoreCoRoutine(String) (at Assets/Script/HSController.cs:35) DisplayUserScore:Start() (at Assets/Script/DisplayUserScore.cs:11)

Why does it have 2 x http? Is is the reason it's failing? If I test the URL straight in the browser I get the high score correctly so my PHP scrips and DB are working fine.

Thanks for the help.
