为什么cookieManager的cookie与Android中的httpClient的cookie不同？

Question

I'm writing a program for Android that sends some POST to a webService with HttpClient like this :

      DefaultHttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("http://example.com/service");
          List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
      nameValuePairs.add(new BasicNameValuePair("email", email));
      nameValuePairs.add(new BasicNameValuePair("password", password));
         // Execute HTTP Post Request
      ResponseHandler<String> responseHandler=new BasicResponseHandler();
      String response = httpclient.execute(httppost , responseHandler) ;

And I tried to retrieve a cookie of "www.example.com" called "Form" like this:

             `
    Log.d("Cookie0" , httpclient.getCookieStore().getCookies().get(0).getValue()) ;              
    Log.d("Cookie1", CookieManager.getInstance().getCookie("http://example.com"));

but the two methods of retrieving a cookie returns two different values for "Form" ! why?

According to the documentation CookieManager is used for cookies in WebViews:

Manages the cookies used by an application's WebView instances

So if you want to get the cookie from your request httpclient.getCookieStore() should be the right way.
