Homephp教程php手册设置图片的HTTP缓存


如果是Apache环境下面,可以在.htaccess文件中添加下面的代码,用于设置图片的HTTP缓存和有效期(需要开启apache的headers模块支持),减少网站的图片资源请求压力,提高访问速度和你的pagespeed值^_^。<ifmodule><br> <filesmatch><br> Header set Cache-Control "max-age=604800"<br> </filesmatch></ifmodule>上面的代码设置了网站的图片使用为期一周的HTTP缓存,当然,你一样可以给js或者css文件加上http缓存哦。
