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>
