Question

我正在使用Google页面速度洞察来提高性能，但无论我做什么，我都无法让'杠杆浏览器缓存'消失。

我已经修改了几个在线文章中描述的htaccess文件，并添加了我能够的所有组合。在页面洞察中，它抱怨CSS / PNG / JS / JPG文件。

# Expires Caching Start #
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType text/css "access 2 day" 
ExpiresByType text/html "access 2 day" 
ExpiresByType image/gif "access 1 year"
ExpiresByType image/png "access 1 year"
ExpiresByType image/jpg "access 1 year"
ExpiresByType image/jpeg "access 1 year"
ExpiresByType image/x-icon "access 1 year"
ExpiresByType application/pdf "access 1 month"
ExpiresByType application/javascript "access 1 month" 
ExpiresByType text/x-javascript "access 1 month"
ExpiresByType application/x-shockwave-flash "access 1 month"
ExpiresDefault "access 1 month"
ExpiresByType text/x-javascript "access plus 1 month"  
ExpiresByType application/x-javascript "access plus 1 month"
ExpiresByType text/x-javascript "access 1 month"
</IfModule>
# Expires Caching End #

Answer 1

你似乎想念你，加上＆＃34;访问加1个月＆＃34;在许多方面。默认值应该是可读性的第二行

以下是h5bp模板的一部分：

ExpiresActive on
ExpiresDefault                                      "access plus 1 month"
ExpiresByType text/css                              "access plus 1 year"
ExpiresByType text/html                             "access plus 0 seconds"
ExpiresByType application/javascript                "access plus 1 year"
ExpiresByType application/x-javascript              "access plus 1 year"
ExpiresByType text/javascript                       "access plus 1 year"

Answer 2

如果你正在使用Apache，你可能想运行这些，因为这对我有用：

sudo a2enmod headers
sudo a2enmod expires
service apache2 restart

您也可以尝试使用此代码：

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

也许试试这个：

# 1 Month for most static assets
<filesMatch ".(css|jpg|jpeg|png|gif|js|ico)$">
Header set Cache-Control "max-age=2592000, public"
</filesMatch>
