如何巧用.htaccess设置网站的压缩与缓存

    <IfModule mod_expires.c>
    ExpiresActive On


    ExpiresDefault A86400

    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>

    FileETag none

例二:

<IfModule mod_expires.c>
ExpiresActive On
ExpiresDefault A0
# 1 年
<FilesMatch “.(flv|ico|pdf|avi|mov|ppt|doc|mp3|wmv|wav)$”>
ExpiresDefault A9030400
</FilesMatch>
# 1 星期
<FilesMatch “.(jpg|jpeg|png|gif|swf)$”>
ExpiresDefault A604800
</FilesMatch>
# 3 小时
<FilesMatch “.(txt|xml|js|css)$”>
ExpiresDefault A10800″
</FilesMatch>
</IfModule>
