常见 .htaccess 用法
顶级域名重定向:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^example.com [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301,NC]禁止图片盗链:
RewriteEngine on
# Remove the following line if you want to block blank referrer too
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http(s)?://(.+.)?example.com [NC]
RewriteRule .(jpg|jpeg|png|gif|bmp)$ - [NC,F,L]
# If you want to display a "blocked" banner in place of the hotlinked image,
# replace the above rule with:
# RewriteRule .(jpg|jpeg|png|gif|bmp) http://example.com/blocked.png [R,L]支持WebP图片格式:
RewriteEngine On
RewriteCond %{HTTP_ACCEPT} image/webp
RewriteCond %{DOCUMENT_ROOT}/$1.webp -f
RewriteRule (.+).(jpe?g|png)$ $1.webp [T=image/webp,E=accept:1]压缩文件:
<IfModule mod_gzip.c> mod_gzip_on Yes mod_gzip_dechunk Yes mod_gzip_item_include file .(html?|txt|css|js|php|pl)$ mod_gzip_item_include handler ^cgi-script$ mod_gzip_item_include mime ^text.* mod_gzip_item_include mime ^application/x-javascript.* mod_gzip_item_exclude mime ^image.* mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.* </IfModule>
增加图片视频等静态文件缓存:
<FilesMatch ".(flv|gif|jpg|jpeg|png|ico|swf)$"> Header set Cache-Control "max-age=2592000" </FilesMatch>
增加文件压缩:
<ifmodule mod_deflate.c> AddOutputFilter DEFLATE html xml php js css </ifmodule>
