1、开启Gzip
<ifmodule mod_deflate.c> AddOutputFilterByType DEFLATE text/html text/css text/plain text/xml application/x-httpd-php application/x-javascript </ifmodule>
2、缓存html 、html、php、txt等文档
<FilesMatch ".(html|htm|php|txt)$"> Header unset Pragma Header unset ETag FileETag None Header set Cache-Control "max-age=600" </FilesMatch>
3、缓存图片、JS、css等
<FilesMatch ".(gif|jpg|jpeg|png|ico|css|js)$"> Header unset Pragma Header unset ETag FileETag None Header set Cache-Control "max-age=604800" </FilesMatch>
但是，如果放了2和3，那么可能后台(/admin)也会出问题，那么就需要在admin目录下放置一个不允许缓存的
<FilesMatch ".(html|htm|php|txt)$"> Header unset ETag FileETag None Header set Cache-Control "no-cache, no-store, max-age=0, must-revalidate" Header set Pragma "no-cache" </FilesMatch>
