I can't get the proper result when updating source code

I’m developing a little project using Yii, Xampp, and Netbeans 7.0, and when I make a change in my code source (for example css/styles.css) I can’t get the proper result due to caching (I presume). please help me get rid of this issue.

I’m sorry for my bad English.

Clean assets dir

Thank for reply.

I have cleaned the assets dir but still can’t get the proper result.

A portion of the main layout code source (views/layouts/main.php) :





<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<meta name="description" content="Agence de voyages et tourisme, Tamanrasset, Djanet, N'Ajjer, Tassili, Ghardaia, Timimoune" />

<meta name="keywords" content="agence,voyages,tourisme,mouflon,sahara,tamanrasset,tassili,djanet,ghardaia,timimoune,algerie,algeria;assekrem" />


<title>voyages dans le grand sud algerien, Tamanrasset, Djanet, Tassili,N'Ajjer, Ghardaia, Timimoune </title>




<?php 


   




    $bUrl=Yii::app()->baseUrl;

    $cs=Yii::app()->getClientScript();

    $cs->registerCoreScript('jquery');

    $cs->registerScriptFile($bUrl.'/js/jquery.easing-1.3.pack.js');

    $cs->registerScriptFile($bUrl.'/js/jquery.nivo.slider.pack.js');

    $cs->registerScriptFile($bUrl.'/js/fancybox/jquery.fancybox-1.3.4.js');

    $cs->registerScriptFile($bUrl.'/js/fancybox/jquery.fancybox-1.3.4.pack.js');

    $cs->registerScriptFile($bUrl.'/js/fancybox/jquery.mousewheel-3.0.4.pack.js');

    $cs->registerCssFile($bUrl.'/js/fancybox/jquery.fancybox-1.3.4.css');

    $cs->registerScriptFile($bUrl.'/js/script.js');

    $cs->registerCssFile($bUrl.'/css/nivo-slider.css');

    $cs->registerCssFile($bUrl.'/css/styles.css');
