指定静态文件缓存的到期日期

Question

当我测试我的网站SpeedTest时,我看到很多过期没有指定错误.你可以在这个页面看到.

我将此代码添加到我的.htaccess文件中

## EXPIRES CACHING ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access 1 year"
ExpiresByType image/jpeg "access 1 year"
ExpiresByType image/gif "access 1 year"
ExpiresByType image/png "access 1 year"
ExpiresByType text/css "access 1 month"
ExpiresByType application/pdf "access 1 month"
ExpiresByType text/x-javascript "access 1 month"
ExpiresByType application/x-shockwave-flash "access 1 month"
ExpiresByType image/x-icon "access 1 year"
ExpiresDefault "access 2 days"
</IfModule>
## EXPIRES CACHING ##

但没有改变.你可以给我一个建议吗,我可以为静态文件指定过期日期吗？

我喜欢html5boilerplate方式:

<IfModule mod_expires.c>
  ExpiresActive on

# Perhaps better to whitelist expires rules? Perhaps.
  ExpiresDefault                          "access plus 1 month"

# cache.appcache needs re-requests in FF 3.6 (thx Remy ~Introducing HTML5)
  ExpiresByType text/cache-manifest       "access plus 0 seconds"

# your document html 
  ExpiresByType text/html                 "access plus 0 seconds"

# data
  ExpiresByType text/xml                  "access plus 0 seconds"
  ExpiresByType application/xml           "access plus 0 seconds"
  ExpiresByType application/json          "access plus 0 seconds"

# rss feed
  ExpiresByType application/rss+xml       "access plus 1 hour"

# favicon (cannot be renamed)
  ExpiresByType image/x-icon              "access plus 1 week" 

# media: images, video, audio
  ExpiresByType image/gif                 "access plus 1 month"
  ExpiresByType image/png                 "access plus 1 month"
  ExpiresByType image/jpg                 "access plus 1 month"
  ExpiresByType image/jpeg                "access plus 1 month"
  ExpiresByType video/ogg                 "access plus 1 month"
  ExpiresByType audio/ogg                 "access plus 1 month"
  ExpiresByType video/mp4                 "access plus 1 month"
  ExpiresByType video/webm                "access plus 1 month"

# htc files  (css3pie)
  ExpiresByType text/x-component          "access plus 1 month"

# webfonts
  ExpiresByType font/truetype             "access plus 1 month"
  ExpiresByType font/opentype             "access plus 1 month"
  ExpiresByType application/x-font-woff   "access plus 1 month"
  ExpiresByType image/svg+xml             "access plus 1 month"
  ExpiresByType application/vnd.ms-fontobject "access plus 1 month"

# css and javascript
  ExpiresByType text/css                  "access plus 2 months"
  ExpiresByType application/javascript    "access plus 2 months"
  ExpiresByType text/javascript           "access plus 2 months"

  <IfModule mod_headers.c>
    Header append Cache-Control "public"
  </IfModule>

</IfModule>

你可以使用mod_headers来做到这一点:

<FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf)$">
  Header set Cache-Control "max-age=290304000, public"
</FilesMatch>

或者你可以使用mod_expires:

ExpiresByType text/html "access plus 1 month 15 days 2 hours"
ExpiresByType image/gif "modification plus 5 hours 3 minutes"

Answer 3

也许您没有加载 mod_expires，因此整个节都是空操作。或者，AllowOverride 为 None，并且您的 .htaccess 文件不会被处理。
