Apache缓存JS和CSS文件

Question

我已经在我的httpd.conf文件中启用了mod_cache、mod_expires和mod_headers模块，并加入了以下文本：

 ExpiresActive On


<ifModule mod_deflate.c>
  <filesMatch "\.(css|js|x?html?|php)$">
    SetOutputFilter DEFLATE
  </filesMatch>
</ifModule>



<ifModule mod_expires.c>
  ExpiresActive On
  ExpiresDefault "access plus 1 seconds"
  ExpiresByType image/x-icon "access plus 2592000 seconds"
  ExpiresByType image/jpeg "access plus 2592000 seconds"
  ExpiresByType image/png "access plus 2592000 seconds"
  ExpiresByType image/gif "access plus 2592000 seconds"
  ExpiresByType application/x-shockwave-flash "access plus 2592000 seconds"
  ExpiresByType text/css "access plus 604800 seconds"
  ExpiresByType text/javascript "access plus 216000 seconds"
  ExpiresByType application/javascript "access plus 216000 seconds"
  ExpiresByType application/x-javascript "access plus 216000 seconds"
  ExpiresByType text/html "access plus 600 seconds"
  ExpiresByType application/xhtml+xml "access plus 600 seconds"
</ifModule>



<ifModule mod_headers.c>
  <filesMatch "\.(ico|jpe?g|png|gif|swf)$">
    Header set Cache-Control "max-age=2592000, public"
  </filesMatch>
  <filesMatch "\.(css)$">
    Header set Cache-Control "max-age=604800, public"
  </filesMatch>
  <filesMatch "\.(js)$">
    Header set Cache-Control "max-age=216000, public"
  </filesMatch>
  <filesMatch "\.(x?html?|php)$">
    Header set Cache-Control "max-age=600, public"
  </filesMatch>
</ifModule>



<ifModule mod_headers.c>
  Header unset ETag
</ifModule>
FileETag None



<ifModule mod_headers.c>
  Header unset Last-Modifiedd
</ifModule>


<IfModule mod_cache.c>

LoadModule mem_cache_module modules/mod_mem_cache.so
<IfModule mod_mem_cache.c>
CacheEnable mem /
MCacheSize 4096
MCacheMaxObjectCount 100
MCacheMinObjectSize 1
MCacheMaxObjectSize 2048
</IfModule>
</IfModule> 

但文件没有被缓存。我得到了像这样的头部信息：

你知道我哪里出错了吗？ 提前感谢。

你如何判断文件没有被缓存？响应头看起来是正确的（Cache-Control: max-age=216000, public Expires: Thu, 25 Aug 2011 23:30:09 GMT）。 - Arnaud Le Blanc

当我在Firebus的网络选项卡中看到状态时，它显示状态200。这是正确的吗？ - user704006

看起来这是一个相当不错的配置。你在Header unset Last-Modifiedd中有一个拼写错误，而且你可能不需要第一行，因为它是<ifModule mod_expires.c>内部的重复行，那里更适合它。
