htaccess利用浏览器缓存图像和CSS

Question

我正在尝试为我的网站创建一个htaccess文件,pageSpeed的见解表明有图像和一个css文件没有过期.

我不知道从哪里开始或如何做到这一点,我从在线教程得到这个代码,并想知道这是否足够工作.

<IfModule mod_expires.c>
ExpiresActive On
############################################
## Add default Expires header
## http://developer.yahoo.com/performance/rules.html#expires
<FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf)$">
ExpiresDefault "access plus 1 year"
</FilesMatch>
</IfModule>

或者这段代码是否符合我的需要呢？

谢谢

Answer 1

尝试类似的东西

<IfModule mod_expires.c> 
  ExpiresActive On
  ExpiresDefault "access plus 1 seconds"
  ExpiresByType text/html "access plus 1 seconds"
  ExpiresByType image/x-icon "access plus 2592000 seconds"
  ExpiresByType image/gif "access plus 2592000 seconds"
  ExpiresByType image/jpeg "access plus 2592000 seconds"
  ExpiresByType image/png "access plus 2592000 seconds"
  ExpiresByType text/css "access plus 604800 seconds"
  ExpiresByType text/javascript "access plus 86400 seconds"
  ExpiresByType application/x-javascript "access plus 86400 seconds"
</IfModule>

要么

<FilesMatch "\.(?i:gif|jpe?g|png|ico|css|js|swf)$">

  <IfModule mod_headers.c>
    Header set Cache-Control "max-age=172800, public, must-revalidate"
  </IfModule>

</FilesMatch>

Answer 2

我知道这是一个迟来的答案,但上述内容对我不起作用.相反,我使用了以下内容:

<FilesMatch "\.(ico|pdf|jpg|jpeg|png|gif|html|htm|xml|txt|xsl|css)$">
Header set Cache-Control "max-age=31536050"
</FilesMatch>

Answer 3

以上答案对我有用,但我也想添加其他文件扩展名.htaccess.下面的代码给我一个很好的解决方案

.htaccess传递Google PageSpeed Insight的完整代码:

1. 启用压缩
2. 利用浏览器缓存

# Enable Compression
<IfModule mod_deflate.c>
  AddOutputFilterByType DEFLATE application/javascript
  AddOutputFilterByType DEFLATE application/rss+xml
  AddOutputFilterByType DEFLATE application/vnd.ms-fontobject
  AddOutputFilterByType DEFLATE application/x-font
  AddOutputFilterByType DEFLATE application/x-font-opentype
  AddOutputFilterByType DEFLATE application/x-font-otf
  AddOutputFilterByType DEFLATE application/x-font-truetype
  AddOutputFilterByType DEFLATE application/x-font-ttf
  AddOutputFilterByType DEFLATE application/x-javascript
  AddOutputFilterByType DEFLATE application/xhtml+xml
  AddOutputFilterByType DEFLATE application/xml
  AddOutputFilterByType DEFLATE font/opentype
  AddOutputFilterByType DEFLATE font/otf
  AddOutputFilterByType DEFLATE font/ttf
  AddOutputFilterByType DEFLATE image/svg+xml
  AddOutputFilterByType DEFLATE image/x-icon
  AddOutputFilterByType DEFLATE text/css
  AddOutputFilterByType DEFLATE text/html
  AddOutputFilterByType DEFLATE text/javascript
  AddOutputFilterByType DEFLATE text/plain
</IfModule>
<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.*
</IfModule>

# Leverage Browser 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 text/html "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 1 month"
</IfModule>
<IfModule mod_headers.c>
  <filesmatch "\.(ico|flv|jpg|jpeg|png|gif|css|swf)$">
  Header set Cache-Control "max-age=2678400, public"
  </filesmatch>
  <filesmatch "\.(html|htm)$">
  Header set Cache-Control "max-age=7200, private, must-revalidate"
  </filesmatch>
  <filesmatch "\.(pdf)$">
  Header set Cache-Control "max-age=86400, public"
  </filesmatch>
  <filesmatch "\.(js)$">
  Header set Cache-Control "max-age=2678400, private"
  </filesmatch>
</IfModule>

此处还提供了各种Web服务器的一些配置.
希望这有助于获得100/100分.
