让Joomla网站继续飞

本站之前针对Joomla加速写过两篇相关文章合理利用joomla cache(缓存) 让网站速度翻倍 、System-cache让Joomla网站速度再翻倍,像子弹在飞
当然提速不止上面两篇，今有幸又得一文来自Joomla.cn的提速教程（以下引自原文）
Joomla网站的页面加载速度一直并不是强项。但其实只要两个简单的手段，访问Joomla网站的速度就会大大提高：
1、先通过插件管理，开启所有的搜索引擎友好链接（SEF)插件，再通过“全局设置”开启Joomla的搜索引擎友好链接（SEF)；注意顺序不能颠倒。
2、用下面的代码替代掉你的Joomla根目录下的htaccess.txt的所有内容，然后将它改名为.htaccess：

# @version $Id: htaccess.txt 10492 2008-07-02 06:38:28Z ircmaxell $# @package Joomla# @copyright Copyright (C) 2005 - 2008 Open Source Matters.

该方法的主要思路是加长浏览器缓存图片的时间。
