Apache静态缓存配置

chj0771

　　Apache配置静态缓存
[root@Linux9 logs]# apachectl -M     #查看expires_modul模块加载
　　expires_module (shared)     

　　

　　[root@Linux9 logs]# vim /usr/local/apache2/conf/extra/httpd-vhosts.conf
　　以下为静态缓存配置:

　　45
46     ExpiresActive on
47     ExpiresByType image/gif "access plus 1 days"
48     ExpiresByType image/jpeg "access plus 24 hours"
49     ExpiresByType image/png "access plus 24 hours"
50     ExpiresByType test/css "now plus 2 hours"
51     ExpiresByType application/x-javascripts "now plus 2 hours"
52     ExpiresByType application/x-shockwave-flash "now plus 2 hours"
53     ExpiresDefault "now plus 0 min"
54

　　

　　[root@linux9 logs]# apachectl -t
Syntax OK

　　[root@linux9 logs]# apachectl graceful
　　
注：ExpiresActive on       #缓存开关 启用或禁产生"Expires:"和"Cache-Control:"头的功能
　　ExpiresDefault "now plus 0 min" #默认不缓存 设置了其作用范围内的所有文档的默认有效期的计算方法
　　修改ExpiresByType image/png "access plus 12 hours"
　　[root@Linux9 apache2]# vim conf/extra/httpd-vhosts.conf
[root@Linux9 apache2]# apachectl graceful
[root@Linux9 apache2]# curl -x192.168.25.57:80 'http://www.yh.com/static/image/common/logo.png' -I
HTTP/1.1 200 OK
