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

# Begin - Rewrite rules to block out some common exploits
# If you experience problems on your site block out the operations listed below
# This attempts to block the most common type of exploit `attempts` to Joomla!
#
# Block out any script trying to set a mosConfig value through the URL
RewriteCond %{QUERY_STRING} mosConfig_[a-zA-Z_]{1,21}(=|\%3D) [OR]
# Block out any script trying to base64_encode crap to send via URL
RewriteCond %{QUERY_STRING} base64_encode.*\(.*\) [OR]
# Block out any script that includes a tag in URL
RewriteCond %{QUERY_STRING} (\|%3E) [NC,OR]
# Block out any script trying to set a PHP GLOBALS variable via URL
RewriteCond %{QUERY_STRING} GLOBALS(=|\[|\%[0-9A-Z]{0,2}) [OR]
# Block out any script trying to modify a _REQUEST variable via URL
RewriteCond %{QUERY_STRING} _REQUEST(=|\[|\%[0-9A-Z]{0,2})
# Send all blocked request to homepage with 403 Forbidden error!
RewriteRule ^(.*)$ index.php [F,L]

ExpiresByType video/x-flv A2592000
ExpiresByType application/pdf A2592000
ExpiresByType text/html A600

该方法的主要思路是加长浏览器缓存图片的时间。
