Waz*_*azy 16 php performance .htaccess yslow
我安装了Yslow附加组件

当我在Yslow中检查我的应用程序时,我得到了Add Expires标题,我不知道

我搜索了SO中的相关问题,Google也发现这种方法合适
<?
header("Expires:".gmdate('D, d M Y H:i:s \G\M\T', time() + 3600));
header("Cache-Control: no-cache");
header("Pragma: no-cache");
ob_start();
session_cache_limiter('public');
session_start();
?>
<html>

但它仍然表明我一样
因为我是新手,我对.htaccess了解不多
请帮助我提高应用程序性能
提前致谢

这只会为你的页面内容设置它而不是像图像和css文件这样的东西,我在你的截图上注意到它说42个文件,大概这些是你的图像,css,js等.
在你的.htaccess文件中试试这个,注意这只有在Apache中启用mod_expires并mod_headers启用时才有效:
<ifModule mod_expires.c>
ExpiresActive On
ExpiresDefault "access plus 1 seconds"
ExpiresByType text/html "access plus 1 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 216000 seconds"
ExpiresByType application/x-javascript "access plus 216000 seconds"
ExpiresByType application/javascript "access plus 216000 seconds"
</ifModule>
<ifModule mod_headers.c>
<filesMatch "\\.(ico|pdf|flv|jpg|jpeg|png|gif|swf)$">
Header set Cache-Control "max-age=2592000, public"
</filesMatch>
<filesMatch "\\.(css)$">
Header set Cache-Control "max-age=604800, public"
</filesMatch>
<filesMatch "\\.(js)$">
Header set Cache-Control "max-age=216000, private"
</filesMatch>
<filesMatch "\\.(xml|txt)$">
Header set Cache-Control "max-age=216000, public, must-revalidate"
</filesMatch>
<filesMatch "\\.(html|htm|php)$">
Header set Cache-Control "max-age=1, private, must-revalidate"
</filesMatch>
</ifModule>
