巧用.htaccess设置网站压缩与缓存

在网站根目录下的.htaccess文件中添加以下代码

<IfModule mod_expires.c> 
        ExpiresActive On 
        ExpiresByType image/gif A2592000 
        ExpiresByType image/jpeg A2592000 
        ExpiresByType image/png A2592000 
        ExpiresByType application/x-shockwave-flash A2592000 
        ExpiresByType text/css A2592000 
        ExpiresByType application/x-javascript A2592000 
        ExpiresByType application/javascript A2592000 
        ExpiresByType text/javascript A2592000 
        ExpiresByType text/html A600 
        </IfModule> 

        <IfModule mod_deflate.c> 
        <FilesMatch "\.(js|css|html|htm)$"> 
        SetOutputFilter DEFLATE 
        </FilesMatch> 
        </IfModule> 

        <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> 

        <FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css)$"> 
        Header unset Last-Modified 
        </FilesMatch>
