+Websocket Client Example
+
+Description:
+A simple websocket client example which send "hello" and "world" to server.
+The server will reply the message it received.
+Once the client received "world", it will disconnect with server.
+
+The SSL websocket server:
+	wss://echo.websocket.org
+	wss://sandbox.kaazing.net/echo
+The websocket server without SSL:
+	ws://echo.websocket.org
+	ws://sandbox.kaazing.net/echo
+	
+
+Configuration:
+
+[platform_opts.h]
+	#define CONFIG_EXAMPLE_WEBSOCKET	1
+
+
+    If using the WSS server:
+
+	[wsclient_api.h]
+		#define USING_SSL
+
+	[config_rsa.h]
+		#define SSL_MAX_CONTENT_LEN	5120
+
+	[example_wsclient.c]
+		wsclient_context *wsclient = create_wsclient("wss://sandbox.kaazing.net", 0, "echo", NULL);
+		or
+		wsclient_context *wsclient = create_wsclient("wss://echo.websocket.org", 0, NULL, NULL);
+
+
+    If using the WS server:
+
+	[example_wsclient.c]
+		wsclient_context *wsclient = create_wsclient("ws://sandbox.kaazing.net", 0, "echo", NULL);
+		or
+		wsclient_context *wsclient = create_wsclient("ws://echo.websocket.org", 0, NULL, NULL);
+
+
+Execution:
+Can make automatical Wi-Fi connection when booting by using wlan fast connect example.
+A websocket client example thread will be started automatically when booting.
+If using other websocekt server, modify the create_wsclient() API and the handle_message() function depending on the condition of the server.
