 ====== HttpClient ======
 ===== Introduction =====
-HttpClient是封裝Http Request行為的Library。我用這個Library已經很久了，網路上可以找到不少教學；因此這裡我只記載一些我自己嘗試的東西。

-==== SSL的Hostname驗證 ====
+  * [[java:httpclient:testSSL|Test SSL connection]]
-最近在評估某個功能剛好談到SSL，也講到hostname的驗證，所以好奇試驗一下HttpClient是否有做hostname驗證。我拿臉書URL做測試:
-<code java>
-	public static void main(String[] args) throws ClientProtocolException,
-			IOException {
-		HttpClient httpclient = null;
-		try {
-			httpclient = new DefaultHttpClient();
-			HttpGet get = new HttpGet("https://31.13.95.36/");
-			HttpResponse response = httpclient.execute(get);
-			System.out.println(response.getStatusLine().getStatusCode());
-		} finally {
-			HttpClientUtil.shutdownHttpClient(httpclient);
-		}
-	}
-</code>
-如果是直接用它的domain name會正常；用ip則會出現以下例外，也證明它是有做hostname的驗證的。
