我已将我网站上的所有JS设置为缓存一周。但是,我需要以更高的频率刷新特定文件。因此我使用FilesMatch来实现我的.htaccess文件中的异常:
<IfModule mod_expires.c>
ExpiresActive on
ExpiresDefault "access plus 1 month"
# CSS
ExpiresByType text/css "access plus 1 year"
# Data interchange
ExpiresByType application/json "access plus 0 seconds"
ExpiresByType application/xml "access plus 0 seconds"
ExpiresByType text/xml "access plus 0 seconds"
# Favicon (cannot be renamed!)
ExpiresByType image/x-icon "access plus 1 week"
# HTML components (HTCs)
ExpiresByType text/x-component "access plus 1 month"
# HTML
ExpiresByType text/html "access plus 0 seconds"
# JavaScript
ExpiresByType text/javascript "access plus 1 week"
ExpiresByType application/javascript "access plus 1 week"
ExpiresByType application/x-javascript "access plus 1 week"
# Manifest files
ExpiresByType application/x-web-app-manifest+json "access plus 0 seconds"
ExpiresByType text/cache-manifest "access plus 0 seconds"
# Media
ExpiresByType audio/ogg "access plus 1 month"
ExpiresByType image/gif "access plus 1 month"
ExpiresByType image/jpeg "access plus 1 month"
ExpiresByType image/jpg "access plus 1 month"
ExpiresByType image/png "access plus 1 month"
ExpiresByType video/mp4 "access plus 1 month"
ExpiresByType video/ogg "access plus 1 month"
ExpiresByType video/webm "access plus 1 month"
# Web feeds
ExpiresByType application/atom+xml "access plus 1 hour"
ExpiresByType application/rss+xml "access plus 1 hour"
# Web fonts
ExpiresByType application/font-woff "access plus 1 month"
ExpiresByType application/vnd.ms-fontobject "access plus 1 month"
ExpiresByType application/x-font-ttf "access plus 1 month"
ExpiresByType font/opentype "access plus 1 month"
ExpiresByType image/svg+xml "access plus 1 month"
</IfModule>
<FilesMatch "^(ga\.js)$">
ExpiresActive on
ExpiresDefault "access plus 2 days"
</FilesMatch>
异常文件位于/sandboxassets/js/ga.js
,我正在使用的 .htaccess 位于文档根目录(/
)。但是,浏览器似乎没有遵守此异常,并为相关文件提供以下标题:
Accept-Ranges:bytes
Access-Control-Allow-Origin:*
Age:0
Cache-Control:max-age=604800
Content-Encoding:gzip
Content-Length:11967
Content-Type:application/javascript
Date:Thu, 02 Mar 2017 15:03:55 GMT
Expires:Thu, 09 Mar 2017 15:03:55 GMT
Last-Modified:Thu, 02 Mar 2017 15:00:01 GMT
Server:Apache Phusion_Passenger/4.0.10 mod_bwlimited/1.4 mod_fcgid/2.3.9
Vary:Accept-Encoding,User-Agent
Via:1.1 varnish-v4
X-Varnish:18808880
604800秒是1周,这是我的 .htaccess 中定义的所有JS资产的默认值,但我需要它是172800秒(2天)。我究竟做错了什么?另外,有没有办法告诉浏览器刷新到最新的标题? Opera将返回31536000秒(1年),这是我最近改为所有JS的1周!
更新:使用以下代码导致我的网站完全崩溃并出现错误500:
<Directory "/sandboxassets/js/">
AllowOverride All
<FilesMatch "ga\.js$">
Expires A172800
</FilesMatch>
<FilesMatch "tww\.js$">
Expires A172800
</FilesMatch>
</Directory>
我首先在<IfModule mod_expires.c>
内添加它,然后立即在它之后添加它并且每次都遇到相同的错误。
答案 0 :(得分:0)
我的第一个倾向是你需要能够使用&#39; AllowOverride&#39;在目标目标块中实现特定文件的覆盖。
<Directory "/directory/to/your/file">
AllowOverride All
<FilesMatch "\.js$">
Expires A31536000
</FilesMatch>
</Directory>

我强烈建议在你排除任何内容之前关闭CloudFlare进行测试。

我添加这个是因为我认为这也是一个排序问题。 .htaccess从根开始,并在目录中运行。
