htaccess代码没有优化网站Joomla的性能

htaccess code not optimizing Performance of website Joomla

本文关键字：Joomla 性能 网站 优化 代码 htaccess | 更新日期: 2023-09-27

我有一个joomla网站，并添加了.htaccess文件，用于使用gzip对其进行优化，并添加过期过滤器。我使用页面速度来分析它的改进程度。但无论我是否添加.htaccess文件，页面速度点都保持不变

我的意思是说，在.htaccess中添加压缩和过滤器应该会改进它，但它并没有做到这一点，即使我删除了.htacccess文件站点也能很好地工作，页面速度指标点保持不变。下面是我的.htaccess文件中的代码

为了检查我是否在.htaccess文件中放错了标签，比如"这是我的.htacccess"，然后网站给出500错误

我的猜测是有更大的问题导致你的分数保持较低。这些问题可能包括：非常大且未优化的图像，高负载的服务器导致网站速度缓慢，以及JavaScript/CSS文件排序。

另一个原因可能是您正在使用服务器上可能不存在的mod_gzip。在这种情况下，应该使用mod_deflate，所以应该用mod_deflate替换mod_gzip，所以这行：

<ifModule mod_gzip.c>

应该是：

<ifModule mod_deflate.c>

只需在htaccess 中放入以下代码

<ifModule mod_gzip.c>
  mod_gzip_on Yes
  mod_gzip_dechunk Yes
  mod_gzip_item_include file '.(html?|txt|css|js|php|pl)$
  mod_gzip_item_include handler ^cgi-script$
  mod_gzip_item_include mime ^text/.*
  mod_gzip_item_include mime ^application/x-javascript.*
  mod_gzip_item_exclude mime ^image/.*
  mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*
